Wow, it's like capitalism actually works.
Amazon entering a market is a huge deal and a net good for the consumer. I live in a city and between Amazon Prime, Amazon Fresh (I never have to go grocery shopping anymore), and Amazon Restaurants, Amazon is quickly becoming the only place I need to do all my shopping. All of this for a low price. They even have Wal-Mart looking at offering same to 2-day shipping.
It's ridiculous to say Amazon isn't some net good for a market.
