I just went on a little spring/summer shopping spree for my daughter I earned 25 Gymboree Bucks online & then went to the outlet yesterday & earned 50 Gymboree Bucks. How do these work? I know they are time sensitive. But can I use all 75 Gymboree Bucks at once? I'm guessing I have to spend a certain amount to be able to use them-do you know how much? I found some info online, but it didn't tell me much. Thanks for any help you might have!!!
