I knoowwww ;< I'm in Norway, and so far there's not many much cheaper options, it's all pretty extortionate! We pay a little more for this but they have no problems with it and it leaves everything, including them, smelling all lovely and fresh so we don't see a reason to change yet!
CDN$1.31 per pound!? ouch! I don't think I could ever justify paying CDN$3,000/year on cat litter (48.5lbs/week)
