As I ponder your answer, DLOHO, I think I may (finally) be getting it. When I list a quantity of ten, Auctiva/eBay wants to know if I'd be willing to give a break on the shipping costs just in case one buyer wants to buy multiple units. Because I didn't fill in that space (since I don't expect to sell multiple copies of the same Blu-ray title to the same individual), eBay rejected my listing. What you seem to be saying is that by filling in that field, eBay will accept my listing. Then, when I sell the first of these ten units, my GTC listing won't simply end. It will continue, so that the next nine buyers can make their own separate purchases. All without my having to re-list after each sale. Is that about the size of it?
