ordering at Apple for store pickup, and financing with AT&T - trade in question

so, apple has trade in value for my old iphone 14 at 195$, and financing with AT&T give me 1200$ in credits over 36 months. Has anyone done this? ordered on apple, picked up in store, traded in phone and financed with at&t? do you get both the 195$ and the 1200$ in credits? its quite confusing. thanks.
