I guess we as sellers need to raise the prices a bit to compensate instead of trying to undercut each other. Like if item is nornally selling for $300 on amazon and on ebay the lowest is like $220 people start to raise those prices to $230-$240 then we can offset some of the new fees. But that would need everyone to be on same page which is impossible to control and people will still try to undercut left and right to try to get rid of their item.
HAHA, nice! An ebay cartel.
