Yeah, it's a business that could work. I was just trying to point out that at that level, the shipping fee dominates, so if the platform encouraged the user to pick multiple books from the same vendor, that would vastly increase either the margin for the seller or decrease the price to the consumer (and probably drive volume up for the seller) The complaint I'm making about the amazon system is the shipping fee is paid per book, with no discount (at least when I looked last. I haven't sold a book for more than a decade, and nearly all the books I buy are on the kindle.) for the customer buying more than one book from the same seller. When I was doing it, sometimes you'd get lucky; some kind soul would buy a bunch of books from me at once, and I got to ship it out at once, and I got to keep most of the shipping surplus.
