Yes, on occasions you can get more for your money from the Canadian store, especially where titles are priced the same on the US and Canadian stores - which can and does happen.
is it worth getting a canadian psn if you already have a us account?
I’ve checked, the sale only applies to Canadian PSN $20 cards
They've permanently suspended my account for some reason, no reason given why as it could lead to me being able to circumvent their security lol
Their twitter says its on the $20 us psn too
