Amazon vs K's Denki

 We went to K's Denki, which is a major electronic retail store, and bought a facial therapy machine for my family. I always check the Amazon website when I buy home appliances. In most cases, I just look at what I want in a store and buy it later on Amazon. However, recently, I've realized that we can buy many things cheaper at K's Denki than Amazon. In addition to it, I think Amazon reviews on items are unreliable. So I feel the benefit of Amazon has decreased.
