I think one of the bigger problems with amazon is that it replaces so many different sectors all at once. I don't think any one single replacement is really solving the problem, furthermore I don't think an internationally relevant replacement for any one sector is that great either.
I guess the most recent amazon temptation was a utility cabinet, I found a nice one on amazon, but then searched and found an equivalent one from Canadian tire.
The hardest thing for me to break is audio books. I use the library but I find it rarely has what I want in stock, I have tried piracy but I can't find a good tracker for audio books and I like supporting authors when I can. Audible is really cheap compared to every store front, especially when buying credits in bulk.
