To be fair Santa only delivers about 6 presents a year, mostly to kids under 4. You have to believe in him, be good for 365 straight days, leave out milk and cookies (elves have always asked for gifts of milk and bread), your parents can't have already gotten you the gift, and be in a situation where suddenly getting a mysterious present won't get you into trouble.
Krampus on the other hand is much more versatile on whom he visits.
