I installed the chrome add on that automatically directs me to amazon smile every time I go. That way I never forget about it. On the phone app, there is also a way to make sure every purchase goes through amazon smile.No problem. Rules are rules. I keep an Amazon Smile link on my desktop so if I'm "just looking" and end up buying something, I don't have to remember to go through Amazon Smile. I'm not going to petition you to exempt Amazon Smile from the prohibition on affiliate links, because it's not that big a deal. But I do feel I have to echo gorb and emphasize that no one would be contributing anything to anybody by purchasing though an Amazon Smile link unless they've signed up for Amazon Smile.
If you aren't using amazon smile, it is a good thing. Doesn't cost you any extra, just part of what you spend now goes to a charity of your choosing.
