FYI,

如果有闲置的旧的苹果设备啊，计算机，计算机的CPU，内存什么的，可以考虑联系一下 BuySellRam.com（当然也有其他的，我只是了解而已）

“We purchase a large amount of computer equipment and components new or used on a daily basis such as, Memory, CPUs, Graphic Cards, Server Cards, SSD & Storage Drives, Laptops, Tablets, all Apple products 5 years or newer, Corporate Smartphones and devices, Test equipment, Lab Equipment, Video & Photo Equipment, Gaming devices and more.”

可trade in的trade in

一般手机容易trade in。那些trade in program，可以讨价还价吗？没有用过。
