There is one merchant that I know of that is offering thousands of electronic products at amazon cheaper prices.

Also, this is a chicken and egg problem. Merchant won't accept bitcoin because consumers don't use it, but consumers won't demand bitcoin because merchants aren't accepting it. Obviously something have to happens to break the mold. If you want to make a "novelty" currency useful, you have to start using it, but no "novelty" currency is guaranteeing to succeed. However, with bitcoin, the situation is changing. More merchants are accepting bitcoin everyday.
