Technically Whole Foods does not themselves do delivery (it's Instacart), while Amazon actually does (Fresh)... Amazon's also working on grocery pickup, which seems perfect for meal kits.
> Amazon Fresh outsources their actual delivery, as well, so no points for that one.
In my neighborhood there's an Amazon delivery truck that drops off Amazon bags by people who have Amazon uniforms on... Perhaps they're 1099, but for all intents and purposes it is Amazon doing the delivery.
Why is it relevant if the delivery is done by contractors of some kind or by the company directly? Amazon probably even has closer control over their network than WF over Instacart, which isn't exclusive to them.
