Prepaid cards lowers your potential loss, however you end up wasting small funds since you have to purchase a fixed amount of reloads and bound to have leftovers not enough to purchase much other than useless avatars.
Also are they selling $10 prepaids for $10 or there's a margin?
So, reloadable debit cards is the best option, then?
I wish Amazon allowed you to buy PSN and Live prepaid cards in an amount of your choosing. Would eliminate any issues.....
