Ok the process of getting the Netspend card is as follows:
netspend.com - apply for card
they will send the card out to you immediately. Once you get the card in the mail you go back on to netspend.com and activate your card/account. Once that is done you can use that account to verify your paypal account because it is a bank account. it's totally free.
So the question is can I use it to purchase any item even though it's free?
In order to use the NetSpend visa prepaid card you'd have to have money on it. Like if you withdrew 5 dollars to paypal you could then transfer it from paypal to the netspend card and use it... and actually netspend accounts are 2 in 1. a checking and a savings. the savings earns like 5% interest btw
