> Amazon is good for some consumers (people who value convenient shopping and fast shipping)

Amazon is awful for people who value fast shipping. They used to let you specify your shipping speed! Now the only option they offer is "it'll get there when it gets there". They also feel free to deliver things well after they claimed they would, once they're willing to give you a delivery date at all.

I actually canceled my Prime subscription this year specifically because Amazon's approach to shipping is so abusive.
