I don't think it's an affiliate link, those have something like tag=AFFILIATE_ID-20 in the query string. I'm not sure exactly what the junk in the URL is, but I'm guessing Amazon uses it for tracking something or another as you browse the site.

If you prefer, here's the same URL with all that stripped out and with the Smile subdomain so that some of the proceeds go to charity: https://smile.amazon.com/gp/product/B00HLPXL80

You should try these for moving a brisket off of the smoker. I have some and they are awesome.
