Hi. Before I pass your question along to someone else (I don't have access to purchases and such for the Shoppe) can you clarify which sort of code you're using?
You said you were using your June code.
In the Choose Your Own Adventure in Scrapbooking: June 2024 thread
found here it says: Sweet Rewards earned in June will be redeemable between July 14 th and 27th.
Or...are you talking about some other June code/reward?
