the price of legos

A car conversation today while Tyler was looking through a lego catalog.

T:  "Mom, this lego kit is only $19.99.  Isn't that cheap?"
M:  " I wouldn't call that cheap.  That's four jars of stones for you."
T:   "I think that's pretty cheap, Diagon Alley is lots more expensive"
M:  "Yeah, well $20 isn't cheap but Legos are just generally expenseive."
T:   "That's because they are SO AWESOME."
