I was happy with my Apple Mail Trade In experience. I was nervous when I got the box because it seems flimsy and the phone is not well protected from getting crushed. But it survived and I got the full trade in amount.
What I did not realize is that you also get tax added to the trade in amount. Living in a high sales tax state, that makes Apple very competitive with Swappa and eBay.
I'll still do an Apple Store trade in next time, but wanted to share a positive experience.
