This is what happens when regulators don't promote a fair marketplace. With no competition, companies like Amazon stop caring and start to optimize to get the last few pennies out of each sale... which results in a drop in quality of the overall service and eventually either a long, slow death or a corporate sale.

Because Amazon has out priced or out delivered many local stores, we don't have those choices any more.

There's a place for companies like this, but they have so many advantages due to size that they have to be watched to ensure they don't step on smaller players just because they can.
