Ur 1st option is to try & settle it with the merchant/person u purchased the item from

If ur unable 2 work it out with them... Then contact Paypal via there support option & explain ur situation to them

They will start the process of getting ur money back

this also if it's a virtual item. i.e. ingame gold, ingame items or anything to that extent your probably screwed cause paypal doesn't support it.

Even if I sent it as a gift I can't get my money back no matter what?

i disagree, most likely will defend the buyer in that case

im not for sure but if he did send as gift he might not be able to send it anyways. unless he paid with cc through paypal then he could dispute it with the credit card company.
