In case y'all didn't hear, Google has been celebrating it's 10 million or billion downloads and for 10 days they are selling 10 apps at 10 cents each.
You've already missed days 1-3.
I've probably spend 60 cents this week. lol
Very nice.
Here is a thread updated daily at XDA that lists all the apps:
