About Halloween Costumes

Founded in the UK in 2012, Halloween Costumes (halloweencostumes.co.uk) has one of the biggest ranges of Halloween and cosplay costumes online, with thousands of products for adults, kids and pets. You can shop licensed products from franchises such as Marvel, Star Wars and Disney, as well as horror and pop culture costumes. Sizes range from infant to plus size, so you're sure to find something that suits you. Wigs, masks, props and accessories are also available, so you can get just a head-to-toe look sorted in one shop. Orders are dispatched from a UK warehouse, meaning quicker delivery times and no costly international shipping costs.


How Do I Apply a Promo Code During Checkout on Halloween Costumes?

  1. Choose a product: Add a product such as the Adult Deluxe Ghostbusters Costume and select the size. Click the purple 'Add to Basket' button underneath the size options.
  2. View basket: Once the product is added to the basket, click the black 'View Basket' button in the confirmation pop-up to go to the cart.
  3. Apply promo code: On the 'Your Basket' page, scroll down underneath the items in your basket. Find the 'Promo Code' section of the order summary on the left and enter a valid code from DontPayFull and click the black 'Apply' button next to the code. The discount will be applied immediately in the order total.
  4. Checkout: After your discount is applied, click the black 'Checkout Now' button underneath the order summary to proceed with payment and delivery details.

Why is my Halloween Costumes discount code not working and what should I do?

  • Code works for selected categories only: Their codes do not cover licensed costumes, group bundles or sale items. See if your basket has any of these. Changing one thing can be enough to make the code work.
  • Double check any regional restrictions: Codes on their UK site apply only in certain regions and currencies. You must search and check in GBP and ship within the UK.
  • Code reuse not allowed: They restrict codes to be used only once per email. If you had the code before, and and it's now expired during a previous Halloween, it may not be valid for you.
  • Clear cookies or change browsers: Their site holds session data that is preventing the reuse or update of codes. Clear cookies or use incognito mode to reset the promo logic.
