I have an Amazon affiliate account and I do put Amazon affiliate links in my posts when appropriate. If you buy something through one of those links (not necessarily the linked product), I get a small commission at no cost to yourself. I disclose my affiliate status on every page with affiliate links and virtually every other page as well. Disclosure matters.

I do not have affiliate accounts with any other businesses.

Sometimes I recommend products. I do so because I bought them and found them useful (or because I've rented them or borrowed them from a library), not because I got a freebie from the company or a PR firm hired me to shill for them.
