My dream for an online store is the following:<p>A magic list that I can add <i>any</i> item to, select a delivery date, and have the backend automatically fulfill each item, at the cheapest price, on time. I want to completely abstract away the concept of a store. I want a to-do list that automatically delivers stuff to me. Additionally, I want a standardized return policy no matter who fulfills it.<p>I want to be able to say:<p>- (3) Organic Roma tomatoes<p>- (6) Sonicare replacement brush heads<p>- (1) Patagonia Down Sweater, Black, Medium<p>- (1) Bookshelf assembly service, in-home, 3/16/19<p>and magically have it fulfilled. One could have a slider to make the tradeoff between speed of fulfillment and cost.<p>Amazon already sort of does this, but not at the best prices. One would hope that in the magic to-do list model, local retailers would be able to outbid non-local retailers, as their shipping costs would be inherently lower.
