Use the code SEA20 for 20% off

How to use this code

1. 1. Copy the code

   Press the button above. SEA20 goes to your clipboard and we open Poster Master US in this tab.

2. 2. Fill your basket

   Add what you want at Poster Master US. The code only shows its value at the payment step, so ignore the running total until then.

3. 3. Paste it at checkout

   Look for a box marked “discount code”, “promo code” or “voucher” near the payment section, paste, and apply. Most shops have it collapsed under a link, so it is easy to miss.

4. 4. If it is refused

   The usual causes are a basket that does not meet the brand's minimum, items already reduced, or a code that ran out. Tell us with the “something wrong with this page” link and we take it down.
