I just traded in my 17 for the 17 (the pro was out of stock and my 13 wasn’t charging so I didn’t want to wait). The lady said if I got ahold of another 13, I could trade it in for $700 in credits if I bought something on payment. Like buy Beats headphones for $200 (applied to your bill) then you will get $700 applied to your bill (both split over 36 months). I thought about buying a $100 iPhone 13 on market place but decided it’s too much work.
