A flash sale is a promotional event offering limited-time discounts on products or services. It typically lasts for a short period of time, ranging from only a few hours to a few days.

The central premise of a flash discount is to create a sense of urgency among potential customers. The ticking clock accompanying these sales aims to fuel the shopping rush and drive immediate sales. Typically, such deal-of-the-day offers offer high-value products for a fraction of their normal prices.

Key Takeaways

What Does Flash Sale Mean?


Note: Other common terms that mean the same thing are lightning sales, limited-time sales, one-day sales, countdown sales, blitz sales, and pretty much any other term that emphasizes speed and exclusivity. Amazon coined the “lightning” version.

Ultimately, lightning sales are a strategy businesses use to promote products or services. Despite such sales being offered for items of high value, best-sellers aren’t as common as other categories. Sure, if a best-selling product has a new version or model about to be released, it will likely get a flash discount too. However, other categories are more common.

Aside from selling merchandise, lightning discounts are important for retailers because they help attract new customers and clear out old stock. A few risks are involved though, including potential website crashes due to high customer influx.

A Short History of Flash Sales

The concept has evolved with the growth of Internet retailing. The mid-2000s was a time of significant traction as exclusive websites began dedicating themselves to this model. Initially, lightning deals were used to sell luxury and designer goods at steep discounts. They’ve since expanded to encompass a variety of industries and products. 

Over time, technological advancements have allowed for better targeting and personalization of blitz deals. This has made them more successful in reaching desired audiences and fulfilling inventory management objectives.

What Defines a Flash Deal?

Limited-time sales have unique features that differentiate them from regular sales or other special discounts. Generally, a flash sale has to have the following traits:

  • Limited time: short duration; from a few hours to a few days, but rarely extending beyond that. Urgency and the idea of “fear of missing out” is a core part of lightning deals.
  • Significant discounts: products or services are offered at significant discounts compared to their original prices, enticing customers to buy.
  • Limited quantity: blitz sales often involve a limited quantity of products. Once the inventory is sold out, the sale is over, further promoting quick buying decisions.
  • Rapid checkout: retailers often emphasize securing the deal that shoppers want. Customers must usually complete their purchase within a short timeframe after the item is added to the cart, as the risk of it going out of stock is marketed as high.
  • Pre-announced: countdown sales are typically announced in advance, creating customer anticipation.
  • Urgency and scarcity: the limited time and quantity of one-day sales create a sense of exclusivity and immediate action, encouraging quick customer purchasing decisions.
  • Specific products: flash sales usually focus on specific products or categories rather than the entire store inventory.
  • Online presence: lightning sales are commonly found in e-commerce platforms, although brick-and-mortar stores also hold them occasionally.
  • High traffic: limited-time discounts are designed to quickly drive a large volume of traffic. However, businesses must have the proper technical infrastructure to support the potentially large amount of website users. Otherwise, the high traffic can lead to website slowdowns or even a complete crash, making it unavailable for a while.

Types of Products with Flash Deals

Deal-of-the-day offers can significantly drive traffic and clear inventory, as shoppers feel compelled to buy by the products’ limited quantity. Here are some common types of products you might see on flash sales:

By Category

  • Fashion and apparel: many clothing brands clear out seasonal inventory or promote new trends with limited-time offers.
  • Electronics: common for gadgets and electronic devices, including smartphones, laptops, gaming consoles, and more. These sales often coincide with product launches or clearance for older models.
  • Home decor and furniture: lamps, rugs, sofas, and other home decor or furnishings are often sold during countdown sales.
  • Beauty products and cosmetics: used for makeup, skincare, and other beauty products, especially when launching new products or promoting a particular line.
  • Travel and hospitality: flights, hotels, and vacation package providers frequently use flash sales to fill vacancies or promote off-season travel.
  • Fitness equipment and sporting goods: products like home exercise equipment, outdoor gear, and sports apparel are often put on rapid sales.
  • Books and educational material: online platforms may offer flash deals on books, e-books, online courses, and other educational resources.
  • Food and beverage: restaurants, cafes, or food delivery services sometimes offer flash discounts to promote special menu items or to increase orders during slower periods.

By Availability

  • Overstocked products: these are items that a retailer has in excess. Quick sales help sell off excess inventory.
  • Seasonal products: items related to specific seasons (like holiday decorations, seasonal clothing, seasonal food items, etc.) often have daily deals towards the end of the season to clear out inventory.
  • Discontinued products: when a product is discontinued, or a newer model/version is coming out, the older stock often goes on immediate discount to make room for the new product.
  • Products with high margins: items with high-profit margins are often given momentary discounts. As the products are more expensive, the vendor will likely make a decent profit even with the applicable discount, especially as the quantity of the product being bought will probably increase.
  • Impulse buys: customers may be inclined to purchase lower-cost items on a whim. These can include accessories, small household items, cosmetics, etc.
  • Promotional items: new product lines or lesser-known products might be put on flash sales to draw attention and generate buzz.
  • Quantity-limited deals: this type of short sale restricts the number of items available at the discounted price. Retailers often leverage this format by advertising how many units are left to raise urgency.
  • Member-exclusive sales: reserved for customers who are part of a loyalty program or subscription service. These sales provide exclusivity, driving membership for the opportunity of early access to special discounts.

How to Run a Flash Sale

Are you a business owner or in charge of running sales campaigns? Here are some tips to help you run an excellent sale and make the most of your promotion:

Best Practices for Flash Discounts

  • Determine the goal of your campaign: is it to drive traffic, increase sales, clear out excess inventory, or something else? This helps focus efforts and maximize the promotion’s visibility.
  • Choose the right products: pick popular, in-demand, or items with high margins to make the most of your blitz sale.
  • Select the right timeframe: the shorter the time period, the more urgent customers will have to purchase.
  • Promote upcoming sales: promote your flash discounts well in advance to give customers enough time to plan their purchases. The typical promotion period varies from a few days to several weeks. You can use email marketing, social media, website banners, push notifications, online ads, affiliate marketing, or influencer marketing.
  • Check your inventory: ensure you have enough stock to meet demand during the sale.
  • Prepare the products for shipping: plan to fulfill orders efficiently so customers receive their purchases promptly.
  • Allow discount codes: a coupon code or a promotion that can be stacked on top of the lightning sale can make it too good to pass up.

Advantages of Flash Offers

  • Increased sales: a sense of urgency encourages customers to make purchases they might not have otherwise made.
  • Customer engagement: rapid sales can help businesses engage with customers and build loyalty by offering exclusive deals and promotions.
  • Inventory management: daily deals help clear out excess inventory.
  • Customer acquisition: express sales attract new customers who might become loyal shoppers thanks to the discounts.
  • Brand awareness: flash sales can help businesses increase brand awareness by reaching a wider audience through marketing efforts.

Disadvantages of Flash Offers

  • Limited time frame: the limited time pressures customers to purchase, which in some cases may result in them actually steering away from the offer.
  • Potentially niche audience: the sale might only appeal to a particular audience segment, depending on what you’re promoting.
  • Decreased perceived value: offering discounts or promotions too frequently can decrease the perceived value of your products or services in the eyes of your customers.
  • Increased workload: running a time-sensitive sale requires extra planning and preparation, which can add to your team’s workload.
  • Lower profit margins: discounts or promotions result in lower profit per item sold, especially if the products or services sold have low margins. However, sales can dramatically increase the quantity sold, so you’re still making a profit.

Flash Deals FAQs

What Are Flash Sales?

Flash discounts are a type of sales promotion strategy where products or services are offered at significantly reduced prices for a very short period. This period can range from a few hours to a few days.

How Long Do Flash Sales Last?

They generally last a few hours to a few days. However, the duration can vary based on the retailer’s strategy and the product or service sold.

Why Do Retailers Use Quick Sales?

They’re used to sell off excess inventory quickly, boost sales during slow periods, introduce new products, or attract new customers. The sales can also generate buzz around a brand and lead to increased customer engagement.

Are Products in Flash Sales Low Quality?

Some blitz sales may be used to clear out older or discontinued stock. However, that doesn’t mean that the products are low quality. Moreover, many flash sales feature high-quality, popular items. Research the specific product and the sale to see if you’re getting a good deal.

Are Lightning Sales Online Only?

While most commonly associated with online retail, they can also be used in brick-and-mortar stores.

How Do I Find out about Limited Time Discounts?

Retailers typically promote upcoming sales through various channels, including email newsletters, social media posts, online ads, and website banners.

What Are Amazon Lightning Deals?

They’re a year-round promotion from Amazon, which works just as we’ve described so far. However, Amazon coined the term “lightning” for these discounts. While the lightning promotions are generally significant, the holidays bring the best deals (or events such as Prime Day and Prime Big Deal Days). 

Offers include exclusive deals, prescription savings, and free delivery. However, the quantity is always limited – buy before the item sells out, as that’s when the deal ends.


Attention: As discounts tend to be high, Amazon restricts shoppers to buying only one item with an applicable flash discount. Also, the discounted item is removed from your cart if you don’t complete the purchase within 15 minutes!

To check out Amazon’s daily deals, access the “Today’s Deals” option in the menu at the top of Amazon.com. From the left-side menu, select lightning discounts. If you’re on the mobile app: 

  1. Tap the three dots menu at the screen’s bottom.
  2. Select “Deals & Savings.”
  3. Select “Today’s Deals.”
  4. Select “Lightning deal.”

What Are Some Examples of Successful Flash Sales?

Executed properly, these sales can generate significant revenue and drive customer engagement for businesses. Here are some companies who do it right:

  • Alibaba’s Singles Day: one of the most successful sales occurs every year on November 11. For example, in 2021, Alibaba made approximate sales worth $84.5 billion on Singles Day.
  • Amazon’s Prime Day: another majorly successful sale, Prime Day is a 48-hour event with deep discounts on thousands of items across all categories. Prime Day 2023 sold over 375 million items across the platform, with Prime members saving $2.5 billion in cost.
  • Xiaomi’s smartphone sales: Xiaomi, a Chinese electronics company, launched the Mi 10 Ultra smartphone in August 2020. According to some reports, the first sale of the product ended in just 10 seconds, with all units sold out immediately.
  • Zara’s biannual sales: Zara employs a similar principle with their biannual sales, dramatically reducing prices to clear out inventory. These sales generate a frenzy of customer interest and purchasing.
  • Steam’s summer and winter sales: Steam, the world’s biggest digital distribution platform for computer games, holds massive sales in summer and winter, offering deep discounts on a wide range of games. The gaming community anticipates these sales events, contributing significantly to Steam’s annual revenue. However, the general duration of the events is 2 weeks rather than just a few days. One reason is that the products Steam sells are digital, so they’re never at risk of running out. Giving a more forgiving limited-time discount allows shoppers to manage their finances better and spend accordingly.

Do Flash Deals Always Work?

No, they can sometimes fail for a variety of reasons. Here are some common ones:

  • Poor planning and execution: if the retailer doesn’t have enough stock to meet customer demand, it can lead to dissatisfaction and harm the brand’s reputation. Similarly, a sale with too much stock can lead to unsold inventory.
  • Technical issues: if an e-commerce site isn’t prepared to handle a sudden surge in traffic, it could crash or slow down significantly, causing a poor user experience and potential loss of sales.
  • Incorrect pricing: if the discounts aren’t substantial or perceived as valuable by the customers, there may be fewer sales than expected.
  • Inadequate promotion: rapid sales require robust promotion to attract customers. If the sale is not effectively marketed, customers may not be aware of it, leading to a low turnout.
  • Lack of exclusivity: if the products offered in the flash sale are commonly discounted or frequently part of other sales, customers might not feel any excitement or buying urgency.
  • Poor timing: if the sale coincides with other significant sales events or busy periods, it may not grab customer attention.
  • Customer service failures: if customers have questions or issues during the sale and don’t get prompt and helpful service, it might sour their experience and deter them from completing the purchase.
  • Complicated checkout process: customers may abandon their carts if the process is complicated and time-consuming.
