Since turkeys gave their life for Americans this weekend, Pixelmator is on sale for half off in the Mac App Store for only $14.99.
I keep meaning to do a screencast showing why Pixelmator is so great as a Photoshop alternative for 75% of what people typically use Photoshop for - so until I do that you'll just have to take my word for it that Pixelmator is a great deal at it's regular $29.99 so at $14.99 it's a steal.
For anyone with a Retina Mac it's also Retina ready with their recent update:
Both Pixelmator’s friendly user interface and its powerful image editing engine are now optimized for the new MacBook Pro with Retina display.
