I'm still with .com but I've been thinking about switching to .ca, but I'm not convinced it's the smart thing to do.
Does anyone know of a large scale comparison? I've done a few pricing spot checks on maybe a dozen titles, and it's pretty inconclusive which is cheaper. Sometimes .com is, sometimes .ca is.
There would need to be a larger sample done to properly answer the question, and I'm not really up for doing that. Maybe someone, somewhere have been though.
