I don't know how it works in eg the US but Amazon's online grocery purchasing experience is really poor compared with literally every other competitor here in the UK in my view. The system of "add goods to a box until it's full based on size and pay by the box" just gets in the way as it's so alien compared with most online shopping experiences. The traditional supermarkets charge a fixed fee based on time of your delivery slot and it's much more intuitive (popular times are more expensive to allow supermarkets to smooth the deliveries). Where I think they do get it right in that sort of space is the Subscribe and Save programme which must cannibalise a fair amount of supermarket purchases. The "set and forget" nature of it works really well for stuff like nappies/diapers (it's a bit more painful for things like toothpaste because the quantities/frequencies aren't quite right). Historically the quality of their fresh produce was also relatively poor (not particularly fresh and lower grade I think, although that just put them on a par with eg Asda or Morrisons) but I don't know if that's changed since the Whole Foods purchase (I'd like to think so).
