Smartsource.com you'll be able to print a coupon for $1 off any One Colgate Toothbrush. Rumor has it that Wal-Mart has Colgate Toothbrushes on rollback for $1.50. So you'd be able to get it for only $.50 after coupon. Please keep in mind that Wal-Mart prices vary alot so it may not be this price at your local store.
Thanks, Money Saving Mom!
