> Amazon is about convenience and variety first, followed closely by price. If you want to drive to Costco and buy the bulk-version of the few choices they have then yes they will be much cheaper. I feel like that's pretty revisionist. For a very long time, shopping at Amazon was about price first, variety a close second, and convenience a very distant third. I doubt so many people would have developed a habit of shopping there so much if the advantages were truly "convenience and variety" first. Amazon's prices have gotten much less competitive the last several years, which has disrupted the value proposition that caused many people to choose it.
