To the person with the Itunes/Walmart cards not working. Due to the requirement of all "merchants" who take your bank cards for payment, to adhere to Regulation "E" which governs the "electronic" banking systems - your credit card issuer - your bank MUST stand behind the transaction and CREDIT your bank account. You call the phone number on the back of your credit/debit card and tell them you have been ripped off and you want to do a "chargeback" on this transaction and that you have all the supporting documents to show you paid and were rejected when tried to validate it. You have 6-12 months to do this and I wish you all the best. PUSH your bank, ask for supervisors, but they must support you and charge the amount back to the "merchant' - Walmart. Walmart IS responsible and if they sell bad cards or are negligent in not protecting them (so thieves get the codes and put the card back to be sold to you) they must refund your money. Good luck
