I saw it first hand, because I was working in the computer department. It's one of the things that convinced me what a joke that whole place was.
Then you take things like the 360 preorder and now the PS3 preorder. The 'simple' problem they have is they did not set a cap on the online order, so it processed transactions until there were no more in inventory. In short, if they were to honor all the online purchases, they would have had none left to sell in the stores.
They've known about this problem for years, but they choose to do nothing about it, because in part they use page hits/views to help negotiate down the bulk price of some of the they buy.
It's just a bad business as far as the consumers go. And I was rooting for Circuit City to whip their ass until CC decided to give the finger to Toshiba and refuse to carry HD-DVD players in their stores.
Basically joe public is down to choosing the lesser of two evils right now between those two, but Best Buy is by far the dirtier.
You don't get commission for your sales, but your managers get bonuses based on your sales of 'cheese', i.e. accessories, warranties, etc.
Yet, you don't get hours unless you sell, so you're in essence forced to sell the bull just to get hours, but see none of the bonuses that come down for great accessories. You just get the 'privilege' of having more than 20 hours a week even though you're a 'full-time' employee.
And take the whole Blu-ray vs. HD-DVD thing right now. Walk into any BB and they will trash HD-DVD and pump up BR despite HD-DVD providing better picture and sound quality for half the price.
Why? Because Sony tied its PS3 distribution to BR sales, so all BBs are under pressure to push Blu-ray. And who gets screwed? The consumer, just so BB can make a few more bucks on their bottom line.
Lame job, lame company, lame business practices.
