I used to think of all prices in terms of age. So, $100 for, say, a house was VERY expensive, because if someone were 100 years old, he/she would be VERY old! If my parents wouldn't buy me some small trinket because it was too expensive, I'd argue, "but it's only $5!" thinking that a 5-year-old is pretty young!
