eBay will not let you upload tracking #'s for multiple sales made going to the same address. Customer used guest checkout and bought 5 items with 5 different checkouts. All items going to the same address. Bought postage on eBay: tracking on the first one, but when I tried to enter the tracking # on the other 4 items, they wouldn't let me do it. Spent 45 minutes on the phone with them, received a lot of grief and bullshoes with them assuming I'm stupid. So if the buyer files for item not received... eBay refused to add the tracking for the items... I'd be out the cash, due to them not allowing a seller to follow their policies. Fair, Ain't it?
