Here's a Walgreens deal for tomorrow: 
Buy 2 Cottonelle Toilet Paper (12 packs), $5 
Use 2 $.75/1 from 7/17 SS (If you don't have those, use 2 $50/1 printables)
Use $1/1 from Walgreens August Coupon book (located by sale ads in the front of the store)
Total: $6.50
Get back $3.50 Register Reward for buying 2 (ends 7/31)
Net cost: $1.50/12 pack!

This deal will only work tomorrow (July 31) because the August coupon book won't be available/valid until then and it's the last day of this Register Reward promotion.
