>> why you think "bolting on delivery" is easy/trivial For someone in the position of Walmart, and with the many startups that doing delivery, it seems realistic. As for why do i think Amazon will win the high end? really, the biggest reason is that it's Amazon. But yes, that's not a good enough reason, but still, they win an awful lot. But maybe there's a chance for instacart to win the higher end, especially by offering the largest variety any merchant can offer.
