I did a search and didn't see any topics related to the store so I'm not sure if this is the right place to put this but technically I guess it may be a bug? When I try to check out from buying a t-shirt and put the coupon code in the discount field I get this message, "Unable to find a valid discount matching the code entered". I tried in both the regular cart check out and the PayPal check out and get the same thing. I emailed support last week but haven't heard back from them so I'm just checking to see if anyone else is having this problem. I signed up for the premium membership on February 20. Thanks, if this is the wrong forum I'm sorry!
