I'm not sure you will find one for sale easily. I tried the Kijiji and eBay thing back in March when I got my phone and couldn't find a 5c case. Ended up buying one at The Source. Not many colour choices (black or grey/white) but I picked up a black one with the belt clip for I think $60 at the North Hill one.

Looks like the majority of stores have a couple in stock of black or grey/white.
