If you have bone or joint problems those rubber puzzle mats are very helpful

I have arthritis among other things and bought about 2 dozen of those mats at Harbor Freight a couple of weeks ago. Was kind of upset when I got home and checked the flier they enclosed advertising them for about half what I paid. They are $5.99 a four pack 2'x2' ea., today and tomorrow. They are about $25 for a six pack other places. These mats have made quite a difference for me when I'm standing at my workbench or walking about on concrete floors. They also help keep the floors warmer. Just though some of you would like to know.
