My only complaint is that I didn't get an adequate quote on their dropshipping service, it was higher than I expected. They answered nearly all of my questions in a timely fashion and were on top of communicating 95% of the things that I needed to know. My experience with Shuffled Ink was extremely positive and they walked with me through the process of printing a custom designed tarot deck that all of my backers dearly enjoyed. Highly professional printers with good turnaround and they hit the expectations they set.
