Whats the minimum quantity of cards I can have printed?
One thousand (1000). This minimum increased from 500 in late 2006. At the time of writing, it is still cheaper to get 1000 cards from Savvy Web Design than to get 500 from many other sources, so it would be well worth your while to ask for a quote. If you only need a small quantity of cards — say 20 or 100 — you would be better off designing and printing them on a home computer.
