3M has a great deal out right now where you can get a free tote bag when you mail in your receipt and two UPCs of Scotch-Brite Greeer Cleaner Products. To make the deal even better they also have a $1/2 coupon. You use that coupon to get two green sponges (around $1 each I believe, so $1 total after coupon) and then get a free tote. Just head on over here and print the coupon and the form. The coupons is a pdf so you can use it more than once – but it does say limit one coupon per day and no cash back (if overage).
If you still have the BOGO Scotch-Brite Greener Cleaner Wipes coupon (no longer available) you can get a great deal on those as well.
