There are quite a few iPad app and game sales going on right now, apparently to kick off Valentine’s Day week. One that has caught my eye this weekend involves the massively popular Angry Birds games for iPad. They’re all down to 99 cents right now – from their standard prices of $2.99.

The Angry Birds iPad titles include these:

Also on sale at 99 cents are Angry Birds Seasons HD and Angry Birds Rio HD.

If you’re a fan of those unhappy, vengeful birds on the iPad then today is a good day to go collect all these games.

Thanks to Cody at iDownloadblog for the heads-up on these.
