u better be sure what u are doing.. if the guy has zero feedback, maybe a good guy or a bad guy.. when i always buy on eBay i tried to buy from a guy with lots of postive feedback, and not only as a buyer but also a seller..
Try to ask him lots of details abt the item and also to send u additional pictures, jst to make sure he really got the item u are bidding for.
If the guy cheated u, u never can have the whole amount u paid, but paypal can give u back some of it.. (not much actually), but be sure to keep every email and the receipt of the winner auction.
But, if the guy didnt cheat u, then dont forget to give him a positve feedback, cos on eBay that kind of ppl is what we need, no that scumback who cheat u (had couple of bad experiences).
Hope that helps!
Cheers
I am buying a digital camera through ebay from a person with zero feedback, using paypal for payment. How risky is this transaction? If I never receive the item from the seller, can I get the money back from paypal, or from my bank?
Any suggestions? Anyone with similar experience? Thanks.
