I recently bought some scales similar to what "Under" is selling. I got 4 - 550g scales for 18.95/per + 7.50 shipping. They didn't come with calibration weights and the display isn't backlit. The weights alone are $4.50 each. All things considered, I think what he's offering is a better deal. Just wish I knew about this a few weeks ago.
Could of put the money I would have saved towards more batteries.
