Interesting. Looks like Best Buy has a class action lawsuit against them in New York claiming that their price match guarantee is a scam.
Well, I'm not surprised. I just experienced it myself. Here's my story:
I won a $250 gift card to Best Buy. I was thrilled, because I've been wanting a good digital camera instead of the cheap point-and-clicks I've been buying up to now. I wanted one with really good zoom, etc. So I thought, I'll put that gift card toward a decent camera. Not high-end, just not low-end.
