This coupon is for $10 off your purchase of $40 or more this Friday and Saturday only. Use it buy into some of the free-after-rebates for September and you could score and additional $10 in savings on top of all that other freebie goodness!
I'm still working out my scenario - and I know that my Walgreens doesn't always carry the full stock of freebies all month long. So I'll just plan for over $40 and adjust as I go. Off to do some coupon compiling!!!!
