Honestly it's been a very long time since I have shopped Walgreens, but their road signage pulled me in!
YMMV on quantity. I just got 3 because I only had 3 coupons:
3 Cottonelle 12pk $4.49 ea
less 3 $1/1 WAGS booklet Q's
less 2 $1/1 MFR's*
less 1 $.50/1 MFR
less $2 "Rewards Redemption" Instant Savings (she just said I had $2 on the WAGS rewards card that I could use toward anything, and said I could use it on this transaction so I did! Wahoo, score!)
= $5.97 OOP + tax, or $1.99 per Cottonelle 12pk!
*This was a regional Q.
