I don't have a lot of inner details about amazon but I do know that they have peaked already as far as retail goes. I don't know when, I just know its happened already.
Amazon is no longer any of the following:
- The cheapest deal
- Filled with reliable reviews
- Filled with trustworthy companies
And on top of that, their product search page is to the point where not even the advertisers are having a good time. The end users (buyers) stopped having a useful interface a while before that.
Its easier now for me to avoid amazon simply because they aren't the best deal by nearly any metric any more.
