Walmart frequently provides links to receive free samples on their website. Their latest freebie is a sample from Kotex for all the ladies out there. Kotex is promoting their latest line of feminine products called "U." You can sample either a pad, tampon, or panty liner.
To get a sample go to this link http://see.walmart.com/u-by-kotex/#/home and click on the "click here" button on the right hand side of the webpage. Once you click the button a form will come up with how to get your sample mailed to your home.
I've received a lot of samples from Walmart in the past so I can assure you this is legit.
