For those that are kind of miffed about the app pricing should frequent this site:
www.appshopper.com
They list all price increases and decreases, including historical costs, so you can make a better decision when you're looking to shop.
Also, Walmart always has giftcards on sale. Currently they have $25 iTunes cards on sale for $20 which works out to $0.80 per iTunes $1. It's not a great deal of savings but it's better than nothing. Don't go to Northland Walmart to get them though. They have a crap load of $10 and $50 but never $25.
