I don't see much in my Rite-Aid ad, so I'm going to suggest you check out Hip2Save's post for this week's deals. And MakingCentsOfSavings has a couple good scenarios too. Rite-Aid's deals vary a lot by region, so check your ad or online to see if the deals they mention are going on in your area.
My favorite deal is the Johnson's Baby Care sale. You can possibly get 10 items for free and quite a bit towards Rite-Aid's "Gift of Savings" program! "Gift of Savings" is kind of a bonus on top of the Single Check Rebates. Between 9/13 and 10/17 you enter your receipts online just like you do for the SCR's and you get RA gift certificates back up to $20 depending on how much you spend from now until Oct. 17th.
I believe the last couple years they've also done the same kind of thing just before Christmas, so they may run another promotion like this later too.
