Walgreens has certain Reach toothbrushes on sale today for $0.99 which, when combined with the $2/2 Reach coupon on Coupons.com, makes them free! My Wags was already out by the time I got there and some people have reported that it didn't work for them, so I wouldn't go out of my way. Still, if you know you'll be passing by one of their stores this afternoon, it might be worth a shot.
Additionally at Rite Aid, Reach double packs are $3.99 with $3 in Single Check Rebates (SCR). After the coupon, you end up paying $2 and can send off for a $3 rebate check. You've got until tomorrow, June 12, in order to make this purchase if you want to qualify for the rebate.
This is the deal I ended up going with (as well as my first time doing a SCR), because I finally realized making a dollar was better than free. Three cheers for public education!
