Another important thing to consider is most of the time in addition to what others have said is that the best price for any given product will usually be at some large retailer (online or otherwise). The key here is MOST of the time. Smaller retailers might have better sales for products, but sometimes they have much worse return policies, or risk going out of business so won't support you if anything goes wrong, and the extra 10 bucks saved isn't worth it. So consumer behavior in the US has essentially learned to focus on the larger national/international retailers. That's why "buy local" is a thing here. People feel that they are somehow supporting their local economy more directly by buying from some local small retailer.
