I just got screwed by UPS. I got a quote on an item that I sold on ebay. It was a trailer hitch for a dodge van. they quoted $17.20. So I got the 17.20 from the guy and shipped it out. Got the invoice today and it was for 36.50. Called them and they said because I entered the sizes differently from the 1st time ie: L X W X H, instead of W X L X H it was calculated differently, and became oversize. Nothing I can do about it.
