We all know not to pay full price for anything at Canadian Tire, but sometimes it is hard to know whether the sale price is good (is 40% off good? Or do I hold out for 70%?). I came across https://stocktrack.ca/ a while ago, which allows you to check stock at various Canadian retailers a little more conveniently than through their own websites, but if you mouse over the price, it also gives you a price history! For that socket set, for instance: https://stocktrack.ca/?s=ct&q=0582028
Maybe y'all new about that already, but it was relatively new to me.
