I love getting free samples in the mail. However, I am not willing to spend 30 minutes filling out surveys to get a freebie.
Walmart.com always has some great free samples offered on their website. You can request these samples in just a couple minutes and by answering just a few quick questions. Samples usually arrive in just a few weeks with coupons included too! Find these under tab labeled "in stores now."
Check back every couple of months. They add and change freebies frequently.
A few that are offered currently include:
Platex Sport tampons
Emergen-C Multi Vitamin
Good Nights Underpants
