Walmart has some great free samples out right now. These usually arrive MUCH sooner than the 6-8 weeks most samples take to arrive. Remember that many free samples come with coupons for the product too so it's two great reasons to sign up. Walmart is really good about not sending a bunch of junk mail after the samples too.
