depends how many you are looking for. i also use the small kitty litter pans. i struck up a deal with the local pet store. i sold them a corn snake really cheap, and they gave me a large quantity of the kitty litter pans, at COST, which was around $2.50 CDN each. not bad
Wherabouts in Canada? Do you breed? You got some nice pairings? Reptile basics has some nice plastic cheap hides!
