Amazon expands its perishable delivery service, putting pressure on traditional grocers

Have people learned nothing about amazons business model?

Undercut competition at a loss to kill competition and strengthen market dominance. Once step one has worked proceed to raise prices and provide shittier service, cut business cost, fuck over workers and customers alike.

If it's cheaper right now, it wont be for long.

I don't like this change (maybe I'm getting old), but it will be interesting to see the economics of this change. I wonder if this can be cheaper than grocery stores, but my gut feeling is that the store would be cheaper.
