D) When selling items, you must specify every item that you are selling, "Selling my deactivated inventory." and other such sales, don't cut it. In addition to this, if you are selling items and do not specify a starting price, then you are opening yourself up to haggling (of items and/or tc). If you do not want hagglers, then place a starting price on your items, if otherwise - don't moan about "stupid bids".
