Discount codes — how to apply one and why it might not be working

How to apply a discount code

Discount codes are entered at checkout. Here's how:

  1. Add your item to the cart and proceed to checkout
  2. On the checkout page, look for the "Discount code" field
  3. Type or paste your code exactly as provided — codes are case-sensitive
  4. Click "Apply" before completing your purchase
  5. You should see the discount reflected in your order total before you pay

The code must be applied before you complete payment. Discount codes cannot be applied to orders that have already been placed.


Codes cannot be combined

Only one discount code can be used per order. If you have multiple codes, choose the one that gives you the best saving — the other cannot be stacked on top of it.


Why isn't my code working?

A few common reasons:

  • The code has already been used — some codes are single-use only and cannot be reused once applied
  • The code has expired — promotional codes have an end date. Check any email or communication where you received the code for its validity period
  • You're trying to combine codes — only one code is accepted per order
  • A typo — copy and paste the code directly rather than typing it manually to avoid errors
  • The item in your cart isn't eligible — some codes apply only to specific products
