Never heard of this site before but CBC’s Market Place did a story that featured a guy that wanted a drill, in the effort to get it for the best price he could he ended up developing an entire website to track Canadian Tire pricing. Probing around the history seems limited to a year on many items but it might be of value to shoppers if they can hold off on an item. The will even send an alert if an item goes on sale.
