You're not thinking wrong. At least not in terms of the math (though you forgot the $2 for a card). But the point of that part of the episode was just to show Sheldon being Sheldon, and the math behind the debt isn't important. Correct math or not, normal people do not view gifts that way. So your math is correct, but you are over-thinking it. Hopefully I've explained this without getting too complicated.
