Not Great
I've done several business card and address label orders with Zazzle. I have returned 3 due to poor print quality, and other errors. blurry, discolorations on the cards, print that was so small that even with magnifying glasses I could barely read it but it looked normal on the website. Some issues were so obvious, I wonder if they have anyone check things before they are sent to the customer. A few orders were fine. They refunded me only to their website as a credit. I should have spent more money initially with an actual print business rather than an online hit or miss website.
