UPDATE: Just got a message from a blogger friend. It appears right now this is only working on Cottonelle Ultra. So be sure you grab the Ultra. I will let you know as I receive updates about what is happening.
Wow has this turned into a thing. The deal is working in some parts of the country and not in others. For right now hold onto your coupons until Walgreens gets this straightened out!
Hot dog! I will be adding some more Cottonelle to my stockpile next week! (This sale begins 10/7)
Check out this hot deal that will be available at Walgreens:
Buy 2 Cottonelle 12 packs $5 each (or $10 total) between Oct. 7-15
Use one $1/1 Walgreens Cottonelle coupon from the October Coupon Booklet (Will deduct $2)
Use two $0.75/1 coupons from 9/11 SS (Exp.10/23) or use the $0.50/1 Cottonelle printable coupons 
Pay $6.50 after coupons, and get back $3 Register Reward
Now remember this is Walgreens so if you use 4 coupons you must have 4 items. So you will have to pick up two small items in addition to the toilet paper in order to complete your transaction. But it’s still a fantastic deal!
Thanks Common Sense With Money !
