Why would you guys order your iPhone from best buy? In my experience with all electronics, they are the least knowledgeable and their prices are not competitive. You would be better off ordering from the carrier or apple itself.
Also regarding accessories, when I was looking for ipad accessories, they had less of a selection than even Verizon. For example, right before hurricane Lorraine here in the NYC area, I was searching for a battery backup for my iPad and itouch and they had nothing. I browsed their other accessories at that point and they were very limited.
Apple was out of stock of backups for the i products and they recommended blackstones. I picked up a cool backup there for my iPad. Touch backup at verizon.
