i mean its a value exchange, the last mile matters a ton to the consumer, the value prop the average person gets from amazon vs shopping in 2000 is insane and scales up the more valuable your time is.

Not only are prices good, but if i lose my remote or need a shovel for the winter or whatever in 2000 im going to a store for that, that 15m of my time each way+parking+less choice.

Lets say i make $50 an hour, and lets say i value my free time at my working rate (i'd argue most people by definition value it more or they'd be working more hours).

Saving me 10m in the store 15m of driving both ways and 2-3m of transit is worth more than most items i purchase.

Amazons solved the last mile problem by having one vehicle bring each item to each home so its marginal cost of delivery is the distance between each home instead of the round trip between home and return that a customer has.

The more items you buy at one store the less valuable this is, which is part of why costco is well served by having such large product sizes.
