It's an affiliate link. (tag=hyprod-20) You can use https://www.amazon.com/dp/B07Z5SPRWM/ instead.

It's not an affiliate link... I just copied the URL my browser gave me.

Did OP make an affiliate link just to earn a few bucks from HN'ers?

If so, I suspect there are better uses for their time...

I was curious so I googled the text "hyprod-20"

It let to a forum from 5 years ago with someone accusing someone else of doing the same thing!

In the end, it seems like it's something google appends to their search

Fun little read for you:

From the other stuff in the url I'm pretty sure OP just copied the link from an ad to Amazon, not created their own affiliate link (which would be crass but par for the course in the techbro hustle we live in I guess)

He could get commission from any sales in the next 30 days

not just this 11$ product

30 days?! That seems shockingly generous for Amazon. What happens when someone has a handful of overlapping affiliate clicks? Do the referrers all split the pool or most-recent wins?

last click wins.
