The player pays the total cost in any order. Partial payments are not allowed.

Example: You play Death Bomb, which costs {3}{B} and has an additional cost of sacrificing a creature. You sacrifice Thunderscape Familiar, whose effect makes your black spells cost {1} less to play. Because a spell's total cost is "locked in" before payments are actually made, you pay {2}{B}, not {3}{B}, even though you're sacrificing the Familiar.
