Special Delivery (S) (1978)

Alice Phelps heads off to the gym, reminding her husband Ralph to shovel the snow from the porch. Ralph ignores her and then later finds that the mailman has slipped, broken his neck, and died on their snow- and ice-covered porch. Ralph panics, and what he does with the body (because he's in fear of the letter carriers' union) and what Alice does upon returning home forever change their marriage.
