Take a look at the freebie being promoted by the NIH. They are currently offering up 3 free coloring and activity books. This is live on their site (link posted below). Visit them, add the books to your cart and go through the checkout process. These will be sent to you for free along with free shipping. This freebie, like most others can take up to 8 weeks to arrive at your door so please be patient. All samples are only available while supplies last.
Sampables does not directly provide anyone with samples or any free items. All samples, giveaways or contests posted are hosted by third party sites or companies.
