I buy this product from my Tescos express and noticed that on their website, there is an option to join their sampling panel
it says "We would love to know what you think about Snackerries, and our future products which are currently being developed. If you would like to join our tasting panel, and get a sneak preview of potential new products, just enter your details below and we will e-mail you next time we are testing a new idea. We will send you the new product to try out, and ask that in return you answer a few quick questions via our online survey".
