Can a seller add a required insurance fee to the invoice price after an auction has closed? I bought an inclusion bracelet. No dustbag included, so I'm guessing no box either. The shipping was high, $12, for such a small item, but I figured oh well, I'll bid. So, I win the thing, then now I get an invoice with the added "required" $4.00 insurance on it. Do I have to pay it? She's saying that she ships prioirty and wants to add the insurance to make sure it gets there safely, yadayada. I know that it will cost her no more than $8 including insurance to put it in the small priority package. It's just excessive. Does ebay ever do anything about excessive charges? Gosh, if I had known she wanted $16 to ship it, I would not have given her the high bid that I did!
