Bracketeer (simple and good, HDR processing tool) is definitely on sale at the Mac App Store. Normally, $29.95 on Pangea's website ( http://www.pangeasoft.net/pano/bracketeer/index.html ). Now listed for $0.99, which seems a ridiculous price.
I like Bracketeer as I prefer natural looking HDRs and that is what it delivers. At this price you have to get it.
NOTE: You missed it, the prices shows $19.99 now.
