Supposedly 2.298 Pounds of Therapeutic Heat

This is a What The Screenshot, but worth the look anyway.  Click the picture to enbiggen.  You can also see it for yourself here. 

Did you spot it?  Take another look.  Right there after the price. Yes that is a per ounce cost for a heating pad.  As if that wasn't odd enough, the math isn't even right.  According to that page the shipping weight is 1.4 pounds, which would make this cost $1.66/ounce.  So we have a product that has a ridiculous per unit price which isn't correct.  Well done, Amazon.
