Indeed, Best BUy does indeed do tracking (well, they use a third party to do the tracking - or at least they did). And would ban buyers who had a large number of returns.I have seen Apple gives a few members here a hard time on this forum with returning stuff...but i can’t remember a specific case.
For me, i once returned a Nikon camera ($2300 worth) to Best Buy (unopened!) and they banned me from returning anything for 1 year! So, it is always on my mind whenever i “try” stuff from Apple.
