For those of you who are not familiar with our Apps for Less posts, they are a great way for us to point out a few good iPhone (and iPod touch) applications available in the App Store that are currently on sale, or ones that have come down to a price permanently that we feel are worth mentioning to our readers.

Today's first application happens to be one of my personal favorites - Pocket Tunes Radio. [iTunes Link] Not only does it have a ton of free internet radio stations you also get the ability to stream Sirius XM channels. And most of the channels that were omitted from the official Sirius XM application are actually available with Pocket Tunes Radio! Howard Stern anyone? Pocket Tunes Radio is now available for a limited time for $7.99 - $2 off it's regular price.

Next up we have a pair of retro games many of you old school gamers should enjoy. Namco's Galaga REMIX [iTunes Link] and Dig Dug REMIX [iTunes Link] are now on sale for $2.99 a piece! Namco has added a nice twist to two great classic games - the ability to play both the original arcade games and new remixed versions with new boss battles, power-up items, etc...

Last up for today we have another great iPhone game, ngmoco's Star Defense [iTunes Link] has dropped permanently to a low $2.99! This is one game that has been covered here at TiPb more than once, so be sure to check it out.

So there you have it, three great applications at low prices that hopefully some of you will take advantage of. If you happen to have an application in the App Store that is on sale and want everyone to know about it, feel free to contact us and let us know!
