Is a Walmart visa gift card the same as a prepaid visa card?

Walmart Gift Card Visa/iTunes Question???

• So someone owed me 5 dollars but he didn't have the money. Instead, he gave me a walmart visa gift card that he already used. He said the gift card the a remaining balance of $5. I checked the walmart website and verified that it did have $5. I used it on iTunes, and still currently using it. Is that safe? Is it okay to use a giftcard that wasn't orginally given to you? And another question; Will iTunes charge you even if you did not put in your credit/debit card number? Will they send you a bill at home so that you can pay what you didn't at the iTunes website? Thank you very much :)

• Answer:

  since it carries the visa logo, its same as a prepaid card, just limit your purchases to the balacne on card
