Which is what all the real-life stores are facing right now. I don't claim to have the solution, but I tend to buy in stores because I enjoy to have my product today, with better service in terms of refund policies, and that I can talk with a human being face-to-face if the thing is faulty.
I live in Denmark where we have pretty good consumer protection, I suspect the difference between Amazon and a store in the US might be a lot different.
