Wicked annoying...I was trying to get my pictures ordered off of FreePrints (app) just now and I carefully selected like 60 pics...went to pay shipping to get them mailed out and for some reason my card isn't working! It should be, there are no ongoing issues with my card. Anyone else have any problems with them today? I've used the app a couple times with no issues already in the past, and suddenly there's an issue.
