1. Read the Bluebird thread carefully. It is long but all of the tips and directions are there.
2. Understand that you must not ever, ever use the term "gift card" when talking to a WM cashier. You are using DEBIT cards. Simply hand them your BB card and say that you want to load $500. (Or whatever) on you card.
Keep your GC out of site in your hand. Follow instruction on card scanner.
3. Be sure you set a PIN on your VGC first. Visa card are easier to use at WM
Than MasterCard.
4. Do not go again until you have done more reading. Bumbling is not good for you or for others that come after you
Good luck
Added: If all else fails....you can purchase a money order with the card. Again, read how to do this also.. Gift cards not allowed but "debit" cards are.
