What could you possibly be "practicing" for?
Mine is $0. I have no desire to pay for something overpriced that is likely on impulse. My kids don't even ask for anything because they've never gotten a "yes".
My wife and I joke around when we see people buying useless crap at Disney (bubble wands, light toys, etc) and always say "The people who shouldn't buy things always seem to be the ones who do".
