Staples (B&M) trade in old computer to get discount

[Realrammstein]

$100 off purchase of a new computer or
$20 off a general purchase of $100 or more
Sounds like a way to get those president's day sale items even cheaper. I know I have an OLLLD 386 computer in a closet somewhere. :D

What constitutes a computer?

Does it have to have ram?hd?cd?floppy?vid?
How about a case, with a floppy?
Or a Case, a floppy, and a mother board?
