When I wanted to build my own mech keeb, the components were available only on AE. On AMZ they were much more expensive.

My experience with keyboard components on Amazon in Canada is that they’re beyond prohibitively expensive. It’s absolutely insane. I could never wrap my head around why… Who’s buying it? I suppose impulse purchases because so many of them are hard to find otherwise, or you have to wait a while for batches?

There's a ton of amazon.com stuff machine-reposted on amazon.ca (plus a $$$ Fedex/UPS fee to get it to you quickly after they receive it themselves in USA).
