The Source, should have some boots on sale from last year, they have multipul locations.
Mission snow and skate, also should have some stuff at discount from last year.
They Royal board shop, carries some brands that you don't see in other stores such as celsius boots and northwave, Now bindings.
Ski celler and snowboard shop. Not sure if they have left over stock.
There is also Abominable (spelling) but that place is a rip off. They advertise a big percentage off but then have the original stick price almost double what it should be. Im sure they are fine on some stuff you just have to be careful.
Boarderline is in Lethbridge, nice place to visit but same thing as above, know your stuff before you go in. the owner sold me a reg width board with size 14 feet (yes i was a noob at the time).
