A couple of years ago, not long before Circuit City went under, I was in the market for a television. Both Circuit City and Best Buy gave me the run around, told me the item was in stock when it wasn't, trying to sell me anything but what I wanted, telling me I had to get the extended warranty, and shuttling me off to the line to get one of their credit cards, etc.
I went to Amazon and ordered the TV by accident. No warranty run-around, no credit card run around. I don't even bother to browse Best Buy anymore.
Best Buy’s (aka Worst Buy) extended warranty is a HUGE profit center for them.
Best Buy’s days are numbered because of bad service and a “survive the scam” customer environment. The internet did not kill them.
