Honestly, I would rather stick my head in to the oven than order anything from Best Buy. I have had the worst customer service at our local ones. I pre-ordered my Google Chrome Book online.
Interesting... I've had the opposite experience and think that Best Buy rocks! They've always been helpful, great customer service, good promotions, etc. I guess a lot depends on your local store and your own experience, but I'd rather shop at Best Buy than most other places.
