I don’t normally buy refills, since the starter kits are mostly free.   In this case, though, I picked up quite a few for a friend with puppies.  need i say more?  Anywho, these were on clearance for $1.74 each at the Maple Ave store in Lisle.  There is a $1/1 coupon in the September P&G insert and I got my 15% library card discount, so total OOP for 12 of these: $7.05.

Make sure to check your own Walgreens for this clearance, since corporate normally sends out directives to all the stores in a district.
