eBay and Craigslist finds

Strange one which I have not experienced on ebay before. Won a krpyto lock for 13.47 and the seller messages me after its done to say he wants to cancel the sale because quote '
I'm unprepared to sell the lock at such a low price. Sorry for wasting you time'. Luckily I havnt paid with paypal yet, but what the fuck, surely set a reserve price then. what now?

Pay for it with paypal first. He might send it to you anyway. If you leave neg feedback but don't pay, he can start a non payment claim against you. You then have to appeal to have the non payment strike removed from your account. Although the messages between you prove that he is at fault, the effect of the non payment claim is that all feedback is removed for that transaction.
If you pay first, he cant start the non payment claim and your money is safe if you pay with paypal.
