Costco sells a lot of paper products like toilet paper, tissues and paper towels. They do extensive testing and market research on staples like these. However, I have never found a Costco that carries any recycled versions of these products.
After checkout there is always a suggestion box where you can leave a suggestion to carry recycled products and if enough of us do so, we could have a positive impact on reducing deforestation. (they really read these I am told)
Thanks
