I LOVE when Vistaprint has this offer available! Right now, you can go here and order business cards (even the premium cards!), postcards, t-shirts, photo flip books, sticky notes, and more for totally FREE! You do have to pay shipping, but it would be incredibly cheap, as long as you select the slowest option. Even with the slow option, it generally doesn't take me long to receive my orders.
If you're wondering about quality, Vistaprint is excellent. Everything I've ever ordered (and I've ordered a lot from them) has been very well-done and professional looking; I've always been happy with them.
So, go on, order away! It's free stuff!
