Thanks to Money Saving Mom for this freebie info:
Go here to request a coupon for a free bag of IAMs cat food from P&G Brand Sampler. I'm hearing reports that you can't sign up for this if you've recently requested something from P&G.
I signed up for it earlier today and didn’t have any problem. I sign up for freebies pretty often, and have on the P & G site. I figure it is worth a shot!
