About Costco

Operating in the UK since 1993, membership-based warehouse retailer sells bulk discounts on food, electrical, white goods and more. You'll see big names like Samsung, HP and Dyson represented, as well as in-house brand Kirkland Signature. There are individual and business members, and 29 warehouses nationwide. Plus, a website which provides a costco.co.uk online store to order from home or pick up. The membership scheme offers wholesale pricing, often below standard retail pricing. For expensive ranges like home improvement or tech, the savings from these discounts can stack up quickly across repeat orders.


How Do I Apply a Promo Code at Checkout on Costco UK?

  1. Choose a product: Browse categories or search for a specific item, such as 'Samsung 65 Inch QLED 4K Smart TV'. Click 'Add to Basket' on the product page.
  2. View basket and hit 'View Basket': Hit the basket icon in the top right-hand corner and select 'View Basket', then click the 'Checkout' button.
  3. Sign in or sign up: Log into your Costco.co.uk account or create one. Only registered members can order and access member-only pricing.
  4. Fill in delivery details: Enter your delivery address. Click 'Continue to Payment' to get to the payment stage.
  5. Add promo code: On the 'Payment' page, find the 'Promo Code' box underneath the order summary on the right-hand side. Paste a valid code from DontPayFull and click 'Apply' to pay.
  6. Place the order: Choose your payment method, enter the necessary details and click 'Place Order' to complete the purchase. Only members can checkout; you just need to ensure your membership is active to get member pricing.

What should I do if my Costco.co.uk discount code is not working?

  • Verify membership level: Some deals only apply to Executive members, if you are on the Standard plan, the code will not work. See if the offer is applicable to all levels before you try.
  • Check out online-only codes: The majority of codes on their UK site apply only to online orders and don't apply to items purchased in the warehouse. If you want to use a code on a item that must be collected in-store, it won't be valid.
  • Keep an eye out for quantity limits: There are some bulk discounts available (e.g. a minimum of 3 units or £100 spend). If you're buying just one item, the code won't work.
  • Clear browser cache: If you've tried several codes from our page and none have worked, either clear your cache or open in incognito mode. This will reset the session data and allow the code to be activated.
