Hardbopjazz, contact the seller and ask him if he will cancel your bid, unless he's willing to stick with the old shipping charge. If he refuses, then go ahead and retract your bid. If you have to go that route, contact eBay as well and tell them what the seller has done. This is wrong, and you shouldn't let them get away with it. However, as I say, I would see if they will cancel your bid first, so it doesn't show up as a bid retraction for you.
