that is an opinion...
my point and the point theclap is trying to make is that this jacket can be found online brand new for 230 and the seller is STARTING it at 280, used. This website is not about buying rare coats, using them and then flipping them to make money, it is about hooking fellow skiers up (that possibly/probably are low on cash) with gear that they will use because they didn't buy a coat that was too big for them...
My suggestion to the OP would be to try and trade it for a smaller size if he likes the coat or start the bidding at a reasonable price and it gets what it gets to...seems more reasonable to me
