i think they make the price pretty steep in the beginning on purpose... For one when i see a 9.99 app i'm like OMG im not paying 10 bucks for some little game on my phone... then they drop the price to 5 bucks and im like awesome!!! but then if you think about it 5 bucks for a game on a phone is still a bit much but you think it's a great price since it dropped from 10 bucks... This is a very strategic way of selling their app... they get the suckers that pay 10 bucks and then they rake in more profit when they put their app on "sale"
dang i gotta get into making some apps lol..

no matter what... i'm still getting monopoly since its on "sale"
