I found tons of Slim Fast High Protein bars (and some Optima as well) today at my local Big Lots.

The High Protein 5 bar boxes were only $3.00. These are not close to expiration date either (12/2010)

I believe Slim Fast is either changing the packaging or discontinuing them because I have been unable to find them at Walmart lately. These are usually $4.58 at WM so I think it was a good deal for $3.
