I am very excited that you now have the Note 8 and went to do an upgrade at the upgrade price shown for $399 then after putting in the cart the price changes to $749.
I'd like to upgrade and pay out my current phone but not at 749...
I have screen shots showing the price shows 399...
We sure didn't mean to create any confusion!
It looks like you might have been targeted with a special offer on one of our Extra Large plans available for existing customers.
I'll send you a PM to take a closer look at your account
