i have always wanted to do the free sample thing but never really felt comfty giving all of my information to the websites to get them. Walmart has a free page where you can get free samples sent to you and at times they also have things you can pick up at the store check out the website http://instoresnow.walmart.com/In-Stores-Now-free-samples.aspx
What are the risks in requesting the free offers from Walmart?:
Walmart states that they will not share your information, but they may send you their own marketing information.
