If you use Mac App Store, you might be interested in a very special sale available now at ZeroNinetyNine.com
The sale includes numerous Mac App Store applications, each of them available only for $0.99!
There is a app Blast which participates in this sale, so if you don’t already have it, be sure to take a look. If you already own Blast, please pass the word to a friend or relative, who probably doesn’t :-).
