How much is a regular pre-paid debit card worth?

I need to buy something online, And my mom won't let me use her credit card.


So i was just going to go to Wal-Mart and buy a pre-paid debit card.


What i need is exactly $25, can anyone tell me how much pre-paid cards are usually worth,


[or anything about them really, i've never bought one]


Thanks!|||They are worth exactly what you put on them. There aren't set amounts. They have various fees that you need to consider, including transaction and monthly fees on some. Read the fine print before you buy.
