Update: It turns out you can also choose to get a $1.00 off coupon instead. This will definitely come in handy!
Right now you can go here to get a free sample of Purex Complete with Zout Free. Sample packets will be sent by mail in about 12 weeks. I'm really curious how well this works, I guess I will know in 12 weeks! (kind of a long wait for a sample)
Mamas Tip If you are new to signing up for samples, you might wonder is it really worth it? I have to admit the sample isn't really worth it most of the time (unless you want to try before you buy), but a added bonus with getting a sample is usually a coupon. It's rare that they don't send a coupon with the sample and most of the ones I have received have been fairly high value coupons.
