Typical cashback from using Recycling Program
My device is an iPad Air 1 128GB, in pristine condition upgraded to iOS 9.2.1 originally purchased in January 2014, and have been thinking about upgrading to an iPad Pro, when I saw Apple offers an recycling program. However, the cost of my original device was £450 and there does not appear to be a chart listing how much cashback I am likely to get to put towards a new device.
Before making any decisions, I would like to know what my typical cashback is based on my iPad's condition and purchase date.
iPad Air, iOS 9.2.1
