I won't directly link so everyone knows I don't get any profit from it,

You can drop a bare url:

https://www.amazon.com/Sawyer-Products-Water-Filtration-System/dp/B07C2WBFVM/

The key bit of info is the part after /dp/ you can cut off any cruft beyond that and still be OK.

You can make the url even shorter by removing or rewriting the description:

https://www.amazon.com/shorten-or-remove-me/dp/B07C2WBFVM/

https://www.amazon.com/dp/B07C2WBFVM/

You can go further with URL shorteners, but they can conceal referrer links. However, this style does not:

http://amzn.com/B07C2WBFVM

Cite for above style link.

BTW, deal seems expired
