Here's a fun one. Last Thursday, I was thinking about buying a portable gasoline-powered generator that was listed online at Walmart.com as a clearance item for $499.
I'd been looking at it for a few weeks because I didn't have a real need, just out of prudence and a bit of paranoia because I live in earthquake country. Then, on Friday the news of Japan's terrible earthquakes and tsunamis reached the US. Having decided I would make the purchase I went to Walmart.com, and lo and behold, the price had changed to $599. Helpfully, the listing assured me that I was saving $99.
Got to hand it to them for their quick reaction. Some people might call this good business, however, in a real emergency situation you can be prosecuted for doing that in some places.
Count on Walmart to be a good citizen. I did not purchase, by the way.
Monetary Loss: $100.
