Apparently you can't post Amazon links on here
You can, but since the last update the site turns them into a sort of banner ad that gets caught by most browser ad blockers. No idea why that happens now, but it results in an empty space on the page if you're running an ad blocker.
I found out messing around one night that if you delete the "https://" from the beginning of the link and start it with the "www." then it won't get converted to an image and will show up as a normal text link. Again, no idea why.
