Canada Your C&C Prices

Well, I don't live in Canada, but my whole C&C cage will only cost me about $20. I am buying the Coroplast from GE Polymershapes, which will only be $10. Here's their locations in Canada: (broken link removed)
I bought 23 grids from a lady on Craigslist for $5. You should try there for cheap cubes.
My fleece will cost about $15.
All in all, it'll be about $35 for the whole thing. I think it should be similar in Canada, if you look in the right places. GE Polymershapes and Craigslist will help you get cheap stuff.
Good luck!

I can get 4'x8' Coroplast for $10 (GE Polymershapes). 16 Grids (4 cubes) 14.99-20% at Bed Bath and Beyond, or $16 for a 6 cube set at Kmart IF the 9-squares across type are in stock. I could not find grids on Craigslist any cheaper

I made my C&C Alternative cage for free! With acrylic and coroplast from the warehouse at the shop here.

I paid $15 per box of grid panels from bed bath and beyond and coroplast sheets from a local sign shop for $20 for a 4' x 8' sheet.

My cage started for less than $5. Got the cubes on Freecycle and used a plastic shower curtain liner. Bought fleece throws for $2.50 each. Towels were discards from friends and my own. Since then I have bought more fleece, cubes for fences and coroplast to make the cage a bit spiffier (in my own opinion). That cost me $25 for coroplast and the Bed, Bath cubes at two boxes at $14.99/box minus $5 coupons. The manager let me use two coupons, one for each box.

my cage costed 43$ 22$ grids and 16$ coro and 5$ for a pack of cable ties but my whole setup was 100 and somthing dollars.

I paid about $18 for each of two boxes of grids from WalMart and I think around $15 for a sheet of coroplast from Rona. I got towels cheaply from Value Village, and then fleece came to around $20. Since the initial setup, I have added more towels and fleece and hidey houses gradually.

I got my fleece from work (Humane society, donated items) and used my own old towels. The grids were 21 dollars at walmart and I got two packs. The Coro was 18 dollars per sheet from a small home improvement store, which is only local. I checked rona and a 4x8 sheet was WAY more expensive than your price.

I got my grids for 29.99 from Canadien Tire and those came with 16grids and 20 connectors. I got my fleece for 15-22$ ,Coroplast from Home Depot for 20$! I got my igloo for 10.99 at Pet Valu and my little balls for 1.00 at Dolarama. I got a dustpan from there too and da garbage can to put all their waste! I got my water bottle from Pet Valu for 11.99 and some hard pencil case bins for the hay and that was 1.00 in total it coster more than 100$ I also got more things I think!
