Dell Home offers downloads of Corel Paint It! for Windows, model no. ESDPIPEN, for $19.99. (You'll receive an email containing a download link within four to eight hours after purchase.) That's tied with our September mention and $20 under the best price we could find for a physical copy of this software elsewhere. It can be used to convert photographic images into multiple styles of paintings.

Note that although Dell lists this as only being compatible with Windows, Corel's website notes that it's compatible with both Windows and Mac.
