For Cyber Monday moo.com had a site wide discount of 30% off. If you don't know moo, you should. They are the ones responsible for the addictive tiny business cards and the super cool concept of 'printfinity' (meaning you can order a pack of 20 cards, and each one can have a different image - catnip for photographers, in other words).
And man, did I ever take advantage of the discount. I think I made like a bazillion promotional postcards to send out to people. Here are some of the fronts of the cards. I think they turned out pretty well, and I can't wait to see them in person, especially since I know how gorgeously their postcards have printed out in the past!
I also bought some of their pretty gold envelopes to send the postcards out in. I know, is an envelope for a postcard really necessary? I say yes! Why not?
If you're interested in trying moo, why not use this link? They'll give me a couple cents toward a future purchase if you buy something, and you won't pay any more than you would have already.
