Uprinting.com is one of the cheapest places for custom printing on the web. I have only used them for color business cards, which I haven't received yet, so we'll see how the quality is.

I also like that they let you review the proofs before they print, so it should be good.

anyway, after my purchase, they had a short survey... and at the end of the survey there was a coupon for 10% off.

Code: SURVEY10

... forgot to mention it's 10% up to $50.
