Colgate Advanced 49 cents Each

Walgreens has Colgate Advanced Toothpaste on sale for $2.99 each.
In the 11/16 paper there were $1 off Colgate coupons.
You can also find them at Colgate's coupon site.

Use either of those in addition to the $3 off (2) coupon in the Easy Saver rebate.

Here is how it works.
Get (2) boxes of Colgate Advanced Toothpaste.
Use (2) of the $1 off coupons. That brings the price to $3.99 for 2.
Use the $3 off 2 coupon and that brings the price to 99 cents for 2.

Not bad because this is the higher quality of the Colgate Toothpastes and some even come with a free toothbrush.
