You can shop on both platforms using your paysafecard, however there is a difference. For amazon, it is simple, just use your paysafecard to buy and amazon giftcard and then shop away! For ebay on the other hand, I would not really recommend this because a lot can go wrong, but if you are desperate, there are sites that are willing to change your psc into pp as that is the only method accepted on ebay, but once again i would probably just leave ebay alone...
