Floss is one of those things that I just refuse to pay for now. I can always get it for free or nearly free. Right now at Wal-Mart, you can get Oral B floss for +$.11! It is regularly $.89 and this weeks PG insert had a $1/1 Oral B floss coupon in it.
Not an Oral B kind of person? Then check out Smart Source QUICKLY to get your $1/1 Reach floss. This sells for $.97 at Wal-Mart for +$.03 overage!
