I am selling a large heating pad (I think it is the largest size available -- approximately 10x14 inches or so) for $8 (it was $15 new). It has 4 different heat settings and automatic shut-off. It has a soft cover as shown in the picture (it is rolled up).

In excellent condition and not used much. Useful to have around in case you have a sports injury etc! Let me know if you are interested.
