I knew that only sellers could get negative feedback now but not this. The reason for that was that sketchy sellers were simply using negative feedback as retaliation for (justified) negative FB from buyers. Seems like there might have been some other solution to that but it would have required eBay man hours to investigate each instance in a timely fashion, (not going to happen), so they took the nuclear option on that.
I still buy stuff on eBay and rarely have a problem, I just return the item for a full refund if not up to snuff. On the rare times a seller balks, I open a case and my $$ is returned post haste. Minor hassle occasionally but plenty of good deals still and fast ship to my door, etc.
Where eBay really sucks is for sellers, IMO. The supply side is saturated for most things and the site doesn't seem to get the traffic it once did for selling the random stuff I have laying around. Plus the fees are high and they charge commission on shipping!

which is another nuclear option to the problem of people charging one dollar for things and bumping up the shipping cost.
