So things did not go to plan today. I went in person to trade in Iphone 13 Pro at Apple store. Started to do trade in and they told me 550. I told them I had been quoted 600 before. The only way to get the 600 is to send it in. I do not want to do it that way but I do not want to eat 50 bucks. Anyway it is packed up and ready, where do I take it? FEDEX , USPS, UPS?
