A coupon may not work if it has expired, has minimum spend requirements, or excludes certain items. Double-check the terms of the coupon, make sure you’ve typed it in correctly without spaces, and confirm your cart matches the eligible conditions before trying again.

RetroStage only allows one coupon code per purchase. If you have multiple discount codes, choose the one that gives you the most savings or check if there are sitewide sales that don’t require a code to maximize discounts.

Some coupons allow discounts on sale items, while others may be restricted to regular-priced products. It’s always best to review the coupon’s terms or test it at checkout to see if it applies to already discounted pieces.

Usually, coupon codes are valid for a single use per customer account unless otherwise specified. Reusing the same code multiple times requires confirmation in the coupon’s terms or may depend on special promotional events.
