Today I went to the store to trade in my mini for a gift card which I plan on using when I trade in my 12 pro for a 13 pro. When I go online and select a 13 Pro with 512 GB storage, the price comes to $1299. I added in a leather cover at $59. So now I am sitting at $1358. With tax of about $100 the total is $1458. So.... here is where I get lost and maybe someone can help me. When I go to check out, I apply the $400 gift card so the price should be $1058 and then I trade in for $640 so my final price should be about $418. If I look at it a different way and take the trade in off the price of the phone: $1299 + $100 (tax) - $640 = $759 + $59 (case) - $400 (gift card) I still get $418. Why is my total listed at $719 on the apple site? No matter how I have been trying to do the math, I cannot get there.... am I missing something?
