Well over the weekend I just happened to be on ebay and figured let me see if there are any good deals on exhaust for my sms 630. Well I found a fmf powercore 4 for $299 shipped. So I did the buy it now and paypaled the money immediately. Now today I get a message from the seller saying he messed up and he will either give me my money back or sell it to me for 432 which he says is his cost. Now I remember a few months ago some guys on here had a similar issue and the seller manned up and sent them for the listed price. I know 432 aint a bad deal but my problem is once that buy it now is used and the thing is paid for its a contract as far as im concerned. The seller should have verified the price before listing it. What do you guys think?
