I didn't get a clear answer on the Discord channels I asked on (that I could spot during intermittent monitoring). So I'll ask here as well.
I see all the vendors are region-locked for the first few minutes, though people expressed doubt as to whether CannonKeys will really be region-locked. (I wouldn't mind buying from them again, in fact, I'd prefer it.)
Is there one of the vendors that will cover South Africa? Normally the European offices with cover Africa, as part of Europe, Middle East and Africa (EMEA), so I think that would be mykeyboard.eu in this case.
Is there anybody that knows?
