Here are several free samples that are currently available:
You can take this Sephora coupon into any Sephora inside a JC Penney store and get a free sample of Givenchy Eau de Parfum. This expires 3/7.
You can also print out an Aveda coupon to take into any retail store for a free sample of Aveda Pure Performance for men dual aftershave. Usually I have found Aveda samples to be particularly small so this is probably not worth a special trip to the mall.
You just need to wait for the offer to load right on the homepage. You will see the little box above in the lower right corner and you can fill out a form to get your coupon.
I mentioned the free sample of Maybelline Fit Me from Target, but it looks like Walmart is offering a free sample as well.
How do they know which color foundation to send? Is it just a coupon for a sample?
