A special thanks to Mashup Mom for the heads up on this one.
Gluten-Free Circle has a section where you can sign up to receive free products or coupons. I just signed up myself so I can't give a personal recommendation on whether this is genuine or not. It was worth a shot for me, though. If interested, go directly to the sign-up page to find more info & sign up!
If you have had personal experience with this organization (good or bad) I'd love to hear it! If you sign up & receive anything, please let me know so I can verify with my readers that they are legit!
