I've been a long time customer of Amazon Prime (around 7 years now) and lately the service has become less valuable and less useful. While shipping is generally fast, I have had two incidents recently where they failed to get me an item on time despite paying extra to get it on a specific date. In both cases, the product was worthless if it did not arrive on time, and after trying to work with their customer support, I have almost give up on them. While I still use some of their other services and have a Kindle that I am hooked on, their 2-day shipping and 1-day shipping options are ultimately disappointing. With the raise in price, I am becoming incredibly concerned about the future of the service. It's becoming more expensive and simultaneously less valuable.
