If you are a Kraft First Taste member be sure to check your account. I just found a coupon good for $2/1 Planters Peanut Butter! This is a nice value coupon, sure to make a decent deal.
If you are not a Kraft First Taste member yet, I suggest to sign up. You may not get in on this deal, but there have been some pretty sweet offers in the past and will most likely be in the future!
