said by Mele20: I don't get the point of those kinds of cards.
There are many advantages/disadvantages to using a prepaid card.
The reasons I routinely them are:
1. Online purchases.
I don't use CC's/debit card for online purchases as a mater of security.
2. To disassociate myself from certain purchases either online or bricknmortar.
The only disadvantage is the ~$5 premium to purchase the card,
I'll mitigate that by buying high value cards to reduce the cost as a percentage of the dollar amount.
