Sold out! Get a free sample of Aquafresh Advanced 2X Whitening from Walmart. Not to be confused with the other free sample offer for Aquafresh Extreme Clean – these are two separate sample offers and Walmart will send you both! See – I told you the toothpaste is free all year long! You just gotta be willing to try new brands & flavors – and visit me every day (ok, maybe once or twice a week but I do like frequent visitors). Update 5/17/08: I got my free sample of Aquafresh Advanced 2X Whitening – no coupon with it.
