Because you told that person that what happened was their fault and that they should be responsible when that is not the case.

I have contacted them. They admitted that it is an issue and to ask the buyer to cover the difference in postage cost.

Flossy63 the problem is that is the price now. When the auction sells and the person actually pays it can be a totally different price depending on their location and the day you are booking on. Ive had this issue for the last year. The only way I get around it is over quoting the postage and refunding as required. It may work for you like your example but there are plenty of us out there that it is not.

Flossy63 is incorrect. I only use Aramex and it's never the same amount.
