A: Of course. They are very cheap. The factories provide the goods. One-stop sourcing.
Q2: Why are electronics so cheap in ok order?
A: On ok order they are the lowest price. Because it is a wholesale website and factory provide goods.
Q3: Do all electronics have silicon in them?
A: No but most modern ones do. Older electronics that don't require micro chips don't have to have silicon at all, and their mother boards are made from copper. Silicon is used in micro chips as a semi-conductor in modern electronics but some other semi-metals, like gallium and germanium can also be used. Silicon is just the most common because it is so plentiful.
