Update: Well...this coupon was one hot mess. Apparently, it was never supposed to be for $3 off any product. They've updated it now and the coupon is now valid for $3 off any $10+ purchase of Yes to Carrots products. As I am understanding it, the original coupon is invalid and should not be used.
After you "like" them, they just want you to print the page and take that to the store. I took a screenshot of the coupon (including the instructions) and printed that. Because they have you do it this way, it is technically unlimited prints, but please use discretion!
Thanks, Money Saving Mom!
