I came across mcmaster.com like 10-15 years ago and I thought its design and experience was amazing. I didn't understand why other sites weren't like this.

Then I talked to regular people (like my friend who builds high-end magic tricks) who happened to use the site and like me wondered why more sites weren't usable like this.

And then after a few years, I saw that people in the comments here and elsewhere thought the same.

And this post is the latest.

I think there's something there.
