Field trip to a (free) children’s heart museum:  About $10 in gas.

A nice lunch for 6 at Big Fat Greek Restaurant:  $65

Redbox late fee for the movie we never even finished watching Sunday night:  $1.20

Standing in line to return said movie, chatting with a bunch of people, and only discovering that the zipper on my pants was wide open AFTER I got back into my car:  Priceless.
