Give them a “like” on facebook and then fill in the form to request yours.
The link above should take you directly to the form but if it takes you to their page, look for the giveaway tab at the top of their page.
Disclaimer: This is not a paid or sponsored post. I like to share offers/samples that I sign up for myself. I always check them out first and only post offers/samples that are legit or appear to be legit to the best of my ability. I cannot guarantee them as they do not come from me. Sign up at your own responsibility.
