Vista Print is having a special for free custom business cards (250) and free standard size postcards (100) and free large postcards (50) until August 17th. The shipping and handling ends up being ~$7.00 and if you only print the biz cards on one side, that's all it will cost! The postcards can be printed on the back--I do mine with the name of the piece of artwork and my name--and the uploads, everything--FREE!
If you'd like me to forward the email to you, email me at karen at ksmithey dot com and I'll forward it.
This really is an amazing deal. I got a set of postcards and biz cards last week, and just ordered more (different) ones today.
They have templates that you can download and use to help you get everything the right size...
