Target just released some new coupons and one of them is a $1.50 off Aquafresh Extreme Clean Target Coupon. It matches up nicely with the 3 other coupons & rebates available for this product and YES, you can use them all on one tube of toothpaste!
Unfortunately, I don’t know the price of the darn toothpaste! So if you find it, please let me know so I can update the post! :)
