While looking for toothpaste at Superstore. I saw that they had Oral B toothbrushes on sale for $1.00.
This in itself is a good price. But I then remembered I had received a $1.00 off coupon in the mail a few weeks back. (I think it's from the P&G brandSAVER website) So it was free!
If you have coupons, check your stash. You too may be able to pick up a free toothbrush.
