When you see a link to a product on Amazon on this website, it’s an affiliate link. This means Amazon knows from this unique link that this website sent you to Amazon. IF you purchase a product from Amazon after clicking on this link, I get a tiny (and I mean tiny) percentage of the sale. This does not increase the price of the item for you!
Almost all websites that have links to stores are using affiliate links. It’s a legal requirement that they disclose this! Because there is money to be made, always make sure a recommendation for a product is genuine!
