Electronics are generally much cheaper in US, but I thought shipping and import fees would make CA cheaper. Nope.
I was looking at ebay, but it's mostly dodgy stuff like 'MK8, no game case, no manual, otherwise good condition. But the artwork says Mario Kart 64, otherwise fine' and it's only like $10 cheaper than just buying from Amazon.
I might have a look at some Second Hand stores and see if they have controllers and games for cheap, but Nintendo prices don't usually drop until they want to clear it out.
