Product change

Hello,

This is the information for my current Macbook (1TB).

MacBook Pro (16-inch, 2019)

2.3 GHz 8-Core Intel Core i9

GB 2667 MHz DDR4

Intel UHD Graphics 630 1536 MB

I would like to ask if I buy the new Macbook Pro (M1 chip), are there any policies that I can change my current one to the new one?

How much my current one can be applied so that it can be directed discounted from the new one?

I am currently a student, is there any further discounts as well?

Thank you.

Sincerely.
