Amazon has done much to eliminate it's competition. We used to have Radio Shack, Fry's, and Toys R Us, and Barnes & Noble, lost of small businesses, etc, now most or all of that is gone and we have Amazon, Wal-mart or other similarly bad company, and a few random small business that might not fit your needs.

Sometimes when I have tried to avoid Amazon by going directly to the company, I find that they sell through Amazon anyways. Amazon needs to be split up by the government. These companies have intentionally made themselves too big and diverse to effectively boycott.
