i really liked working with nextdayflyers.com the customer service was great. i designed my own online, and uploaded and they printed them for me. i got 1000 for 80 shipped. not sure if that is a good price, thats the only time i've ordered post cards so far. they were only 4X6 cards, full color front, and black and white back. it would have been cheaper if i had gotten more of course. just checked gotprint.com, thinking i may try there next time.. the prices seem good!
