I almost always hold off on purchases for a few days to compare what I eventually put in my cart (if anything) to ad-served competitors. There's usually very little overlap with them and the products I was already looking through, so it's a nice additional avenue of shopping around. Sometimes the ads include discounts/promotions as well, which is an added bonus.
