There is an awesome deal at Walgreen right now through 2/22. You can score an 80 piece dentyne ice bag for $1 with the blinking and points back.
Here's the deal:
Denture Ice 80 piece- $2.99
$1/1 in store blinking
Pay $1.99, get 1000 points back (which is like $1)
Also works on the 60 count canisters. I bought one to refill with all my bags.
****Please be courteous and don't clear out the blinking machines or the shelves. :)
