They were making noises about speeding up delivery to a lucky few people in chosen urban areas but in my rural area Prime shipping has slowed down considerably and they seem to make no effort at all to get Prime deliveries to me in two days. It is irksome because sometimes I've decided to buy something at Amazon rather than another store on the assumption I could get it in two days instead of two weeks, so it is an unfair form of anti-competition.
Contrast that to shipping having sped up for most other major retailers (say Best Buy, Walmart, ...) such that I often get things in one day with free or low cost shipping.
My falling out with AMZN started when I saw obviously fraudulent product listings and contacted AMZN only to be told they didn't care unless I had bought the product and been defrauded.
What they don't seem to get is that when they have this attitude it calls into question whether I can trust ANY product listings on AMZN.
