All my Apple products have been purchased from Best Buy (except iPad 3 which I had engraved), why? Because of the Reward Visa that I have with BB. But I dread buying Apple products everytime I go to BB – you never find someone that's free, I'd have to hunt down employees or stand next to one as they helped other customers (which took up to 30 minutes once) and wait for my turn. And after telling them what I exactly want, they'd disappear for 15 minutes in the backroom, only to come out with the wrong model, another 15 minutes before they tell me they don't have it in stock.
It's a horrible buying experience but I endure it for points (especially when one spends thousands of dollars, it can really rack up). It's the only reason why Best Buy still gets my money.
(If Apple had their own Loyalty/Reward kind of program on top of their customer service, it'd be so full of win.)
