Thats still Amazing low cost considering what has to be done to deliver a parcel. Though I'm more surprised Amazon hasn't set up an Argos style business in high density cities.
For those that dont know Argos it's in the UK and its basically a collection shopfront with catalogues infromt of the counter. You browse the catalogue, write down the numbers and staff go out the back and bring you what you asked for. They have a huge range and while strange at first shopping in person from a book catalogue it works amazingly well for a bunch of shopping needs. It would merge perfectly with a Amazon like business.
