Re: If their US Pantry
I stick to bulk ordering long life stuff through Amazon, sacks of flour, pulses, rice etc. That's almost everything we used to need supermarkets for and massively cheaper. Almost everything else is cheaper at our local farm shop or the market and ready to eat today, not in a couple of weeks or likely to rot before ever ripening supermarket style.
The surprisingly large proportion of people that think the big supermarkets are actually cheap are a tempting target for Amazon because loss leaders aside, it will be trivially easy to crush them on both pricing and choice. For the few of us that live happily with minimal exposure to anything beyond Aldi, don't see any change coming we didn't already buy into, we're reverting to buying from the best supplier for each product, not the hell of the supermarket shopping expedition.
