Basically it's another way to get prototype-quality printed circuit boards manufactured and shipped to you.
They're explicitly saying the quality is not top-notch, but compensating with the price level to target prototype runs.
With only two pricing tiers (5x5 cm for $12, 10x10 cm for $24, both include 10 copies of the board and global shipping) it's really simple and very cheap.
It's by the people at Dangerous Prototypes (http://dirtypcbs.com/) so I'm pretty confident they have plenty of experience in dealing with pcb manufacturing houses.
