If you want free Wisk tablets, go to Target or any store that carries the sample size and look for the sample packs. At Target they are located in the Health and Beauty area (for some reason) along with the other sample size products. In each pack is a coupon for $1.00 off any Wisk tablet purchase. The sample packs are .49 each so you can get 2 packs for free plus tax. And yes you can use the coupon on the sample size as there is no exclusion on these coupons.
