iPhone 8/8+/X parts are becoming more available

I can get several parts for 8/8 Plus and X phones now. Screens, batteries, rear glass and rear case, cameras & lenses, speakers, charger ports, etc.
Prices for some of these parts are also dropping since they are becoming more readily available. I imagine that when the iPhone 9 is released, prices for 7 parts will become very cheap and parts for the 8 series will become plentiful and even more affordable.
