Where can I buy Nexxus products in Toronto, Canada?

I currently have the nexxus sleektress shampoo and conditioner. I bought them from shoppers drugmart and they were so expensive and the bottle sizes are very small. I have seen bottles of nexxus products that are fairly large that come with a pump. If any one can tell me where else in Toronto these products are available please let me know? It's urgent! I need to save my hair now from all this breakage and damage!
