I just bought a modestly priced LCD TV at Best Buy. On a lark I asked if they would match B&H's price, which was $100 cheaper. They did, and also took 30% off a cheapish stand.

I am used to negotiating, but this was a complete and pleasant surprise.

just FYI. worth trying in any event.

the first of a couple dozen reasons why they're basically a flea market

negotiate as part of my job, and am amazed that many just assume that a price is a price.
