Today is double coupon day at Walmart if you didn't know you should consider shopping there on Tuesdays. Here is how it works if you have a .40 cent coupon they double it to .80 cents making them an even better deal. They match your coupons for anything under a $1.00. If it happens to be above .50 cents they round it up to a dollar off. My total was $18.57 with tax for 29 items making them around .64 cents an item retail value $42.57.
