I actually think that’s goodwill policy not to sell bulk lots in stores and send them all to a central listing place. They actually have their own auction site…but there aren’t any deals that I’ve ever seen there.

as to your specific listing, there are 4 more days. it will sky rocket. just based on resell value though, I wouldn’t pay more than 60.
