I would recommend that you buy SuperGlides. Not only because the dudes at SuperGlide are awesome supporters of our sport but SuperGlides are definitely a better product. My flat deck (manufactured in the States) had another brand of glides on it and they didn't last a season as the plastic was more brittle than the SuperGlides. I had to replace the pieces on the ramp due to "cold weather cracking".
They say Princess Auto has occasional sales on them but I am sure you can contact Randal at SuperGlides and he would arrange something.
Princess Auto had a sale last year and I bought 4 boxes at $69.99each, they might be having a preseason sale I would ask them.
Nothing wrong with the super glides, but here's another option. I'm trying these Gators, sold in Spruce Grove. Quality looks good, install simple, just have not tried the sled on them yet..

arent they slippery to walk on ?
Well the gators don't have those little spikes like the super glides. The gators are not hard shiny plastic, sort of a mix between rubber/plastic. There was a couple inches of snow on the trailer this past weekend, an they did not feel slick to stand on.
