Deanna, I don't understand why you wouldn't say that you thought it was $19.99...even if you were wrong, it wouldn't have been a big deal.

And your daughter needs to know the value of money. I can see you care for her and didn't want to disappoint her because her heart was set on it, but there's nothing wrong with saying "sorry it's just too much money". I'm sure she would have gotten over it.
