As an aside, the amazon fresh packaging is great as trash bags. The ice packages they send along are great to put in your freezer and use later on trips. They recently (at least to me) added a durable cloth-based cooler, which they say you can put on your porch and they will reuse. I may let them have it back or I might use it as a cooler for my normal grocery store trips.
It is slightly more expensive, but the bottom line is that in the middle of the week I am just too worn out to go to the store, so being able to have a mid or end week delivery means that I have stuff at home instead of having to order out.
I guess I qualify as an amazon fanboy ;-)
Relevance to this HN story, I think they can probably leverage this to help their Amazon Fresh business.
I've tried a bunch of different grocery delivery services (Seattle area) and Amazon Fresh is far and away the best of them. I stuck with Safeway for four months and literally every single time they delivered an order, there was a problem with the order. Every single week! There was always something missing (not even obscure stuff - once they claimed to be out of bananas, for example) and the packaging was terrible - just getting the bags from my front door to the kitchen often let to something falling out and breaking.
Amazon Fresh does things very, very well. They show up on time, almost never have a stocking issue and the packaging is very well designed - the frozen stuff is packed with dry ice, the cold stuff with an ice pack and the rest are packed into reinforced paper bags that are sealed to prevent stuff falling out en-route. It takes only moment to move everything into my kitchen and I've never had something break en-route.
Customer support is much better too - every time my order was missing an item, I'd have to call Safeway and often I simply couldn't reach someone (especially outside of 9-5).
Grocery stores need to up their game quickly or they will go the way of Sears and K-Mart.
