If they're not bidding, forget 'em. Lots of people will whine about your shipping cost, and never bid on crap. Your shipping's fine. It cost $6.00 to ship Priority Flat Rate Small Box, and I don't know of anyone that lives at the post office, so it costs you to drive it there. If you're getting bids, tell the whiners to block off. There's NO LISTIA RULE that says what you have to charge for shipping, only that is has to be fair and reasonable. $7.00 is fair and reasonable.
sorry i am removing this due to too many people having issues with the item and shipping at that what it cost me to ship in the packaging i use to make the item protected as it arrives is what i pay
