you can make one for like $1. seriously. get a sock, fill it with uncooked rice (not like instant rice, real regular rice). Tie or sew the end shut and there you go. don't microwave it for more than 2 minutes

Wheat packs. You put them in the microwave with a cup of water for 3 mins. Any longer and it will burn the wheat. They are about $14
