FYI, reddit's spamfilter doesn't like URL shortenners, unfortunately including the shortenner that the amazon app uses. (I've manually approved your comment).

The best way to post links to amazon is to post the full link, while removing everything after the product code. That removes the affiliate portion from affiliate links, which is important becasue it's easy to accidentally generate an affiliate link if you e.g. initially browse to amazon using one.

For example: https://www.amazon.com/dp/B011WUZEBG
