Shipping charges delay. I hate getting ding for late shipping charges. Sometimes I get billed 45 days after I shipped an item. Plus, why cannot FedEX or UPS get their shipping estimates right either. I ship using correct weight, size etc. FedEx gives me an lowball estimate to ship. I stupidity trust their estimate to ship then get a charge for four or five times the amount. Seriously considering not using ANY of eBay shippers.
