Besides being able to try new products for free, you usually get a high-value coupon that can help with couponing down the road. I got my first sample today, some Vaseline lotion and a $1 off coupon. That paired with a target or other store coupon has a lot of potential down the road (especially if I can find a great sale!)
So give it a try:) For more money saving tips check out my Money Stretcher section. I plan to add some new articles soon, but there are several there already.
