Aluminum Channel

[ponokareefer]

I am looking at doing a DIY LED light system and was thinking of using aluminum channel instead of heat sinks to save a few bucks. Unfortunately, the only places I can find that sell it in central Alberta would charge more for the channels than what I would pay for heat sinks. Does anyone know of a place in Central Alberta that sells this stuff for cheap? I would think online would be quite expensive as shipping would probably cost a lot due to size.
