Right now at Walgreens you can get Crest Toothpaste for just 04!
Crest Anticavity Toothpaste is on sale for $2.29. Use the $1.50/1 coupon that is in Walgreens February coupon booklet (get it in the store). Along with the .75/1 PG coupon that was in the 2/7 newspaper. Your final cost will be .04. If your store is out get a rain check the Walgreens coupon doesn't expire until 2/28.
I sometimes find that the store runs out of these great buys (especially in Utah). If you find your Walgreens is out of the Toothpaste ask for a rain check. Also, Walgreens usually gets 1 truck in during the sale so if your store is out, try finding out when their truck comes in. My Walgreens restocks on Tuesday Morning, so I have the best luck then.
