I go for peace of mind and not getting my items wreaked, since I have buddies there that are awesome and don't give a crap about corporate culture. My local Best Buys aren't that great in store, anyways.
You guys have better GS than me. The one good one near me where no one asked for preorders and didn't bother me closed down like a year later. The employees and manager were nice.
What state are you from? I'm in CA. I did get charged taxes though.
EDIT: Maybe being a Power Up member makes a difference?
