I might be able to organize one for Canada for our lemmy.ca, piefed.ca and sh.itjust.works (and other Fediverse server users who live in Canada) peeps...

I'm not sure who would be comfortable with sharing the address attached to their real name or username on here? I move around too much to be able to organize collecting everything in a PO box and sending it to people, it would rely more on giving random people another user's address and people directly shipping to each other...
