It would be really good if, when you are looking at a product and you see the price across the retailers, if you could click on the retailer you want and see the price history for the product you are looking at. E.G. I am looking at Odor-Eaters Spray, I can see the current retail price for all retailers. I'd then like to be able to click on a specific retailer (e.g.sainsburys) and be able to see the price history for Odor-Eaters in Sainsburys so I can see when in the past it was cheaper or more expensive.
