Where to buy? ... - T1B47

Yesterday I went shopping around Canadian Tire, PJ's petstore, and Superstore to look for pH paper and all the other material I need for my science fair experiment. Guess my luck. If you guessed 0, ding-ding-ding, unfortunately, you're correct. I can't find it, and I need if for my project. Help? If you know where I can buy a small vile of pH paper, please tell me. I'm trying to avoid ordering online packaging. Really, is it too hard to walk/drive to a store? Just saying...
