Same goes for any time you list a link to a product on a online retailer’s page, especially places like Amazon.
I don’t mean to single anyone out, but as an example look at the second post in this thread. That one is like fourteen lines long on my phone screen.
As a general rule you can strip out everything after the first question mark ( “?” ) in the link, including the question mark, and the link will still work. I test my work when doing this but it seems to work in general.
I sometimes wonder if links get left in this forum to track, and perhaps take commissions ? ( That’s done other places, right ? )
