If you're looking for a deal on letterpress business / calling cards, and you're okay with black as your ink color, you might want to try Mandate Press. You get a box of 250 cards for $95, but now, they're offering them on sale for $75! Amazing. You even have the option of supplying your own design if none of their templates strikes your fancy. I could see tons of freelance designers going wild with this option! Turnaround is 2-3 weeks and ships out of Utah.
