First of all, when it comes to fees and the like, bluebird is awesome. It doesn't cost anything to add money and there are many fee free atms available.
However, be careful not have several failed attempts to add money. They will close your account. I visited a local Walmart to add money yo my card. The girl helping me was new and ended up trying to do the transaction 4 times before seeking help. Amex closed my account because they said I was in violation of 22d of the membership agreement.
I have called them and spoke with a supervised and I was informed that I could apply for another account but no guarantee that I would be allowed another account. And there wasn't anything they could do. Regardless of the fact that it was no fault of my own.
