I live in Seattle Washington, I called 1-800-543-3308 which is the company who makes Ferret L'Avian foods. If you buy 10 bags of 20 pounds each, you can get two free 20 pound bags. You do need to keep the UPC Bar Code and cash receipt... Hopefully, some of you will keep this info or either share some of this with shelters... One one way to help shelters or yourself, depending on how many ferrets you own.. Debbie [Posted in FML issue 2970]
