Muir Glen coupons are a favorite of mine. Print this .75/1 Muir Glen product coupon (twice!) and pick up some very inexpensive tomato paste at Walmart. The price has gone up a few cents and is now 98 cents, so pay only 23 cents for each can with this coupon.
This is a fantastic price for tomato paste, especially an organic variety! Use it in your favorite spaghetti sauce!
