Online PC parts

I hope avoiding Amazon fits this community rules?

I need a few bits to resurrect an old PC. My Amazon cart is $68 with shipping - we're going to cancel Prime, but my wife is still working on downloading all her photos. Best I can do elsewhere is near double this PLUS shipping from 3 different suppliers and 2 of the suppliers are on eBay, which is also a US company.

I moved to Canada a few years ago from Australia where I had pccasegear, scorptec and others. It seems Canadians have become reliant on the US market and Amazon and we now have no competitive local retailers for this type of thing?
