these days you can probably get 500 full color cards printed by them for that price, or at worst $20. They've got promocodes all over the web for first time orders.
i had designed our cards for the store some years back. we used pics the boss had taken of marine fish in our tanks, overlayed the text on them and sent em in. i might have spent 15 mins each in photoshop to do them up (everyone got to pick their own custom background image)
but even without PS skills.. the template stuff at vistaprint is good enough to get you a basic design done with very little effort and image manipulation skill.
