Skippy Peanut Butter, Creamy, 40Ounce is only $5.18 right now Amazon.com when you “clip” the $1 off coupon in the middle of the webpage!
This is $0.12 per ounce which is my stock up price! Note that you can only use the coupon at Amazon once. Shipping is Free with Prime or a qualifying order of $25 or more. (I love Amazon Prime specifically for deals like this!)
