if you really need to get a fridge why not get a second hand one?
I mean they are like a couple hundred dollars (if even that...)
and yeah...BC has great weather and you don't really need a fridge to burmate your snakes. Heck even in Ontario I don't need a fridge to burmate the snakes. I just open the windows a bit and cool breeze of cold air floating in....nice and cool for the snakes (just make sure that you don't open too much window in Ontario..you'll freeze, the snakes will freeze....lol
