I found Betty Crocker boxed potatoes on Rollback this morning at my Walmart! There is a new $.50 off Two Betty Crocker Boxed Potatoes printable available! If you don't see this coupon, change your zip code to 53027 and sort by "Foods".
I did notice that the Twin Pack boxes were only $.25 more. So basically you are getting an extra package for only $.25 more. Seems to me that the Twin Pack is the better deal....
Betty Crocker Boxed Potatoes $1.25
Betty Crocker Boxed Potatoes Twin Pack $1.50
$.50 off Two Betty Crocker printable
= as low as $1
