I am emailing because I am ECSTATIC!!!! I would like to thank the graphic designer who worked on my card as well as the staff that turned it out in remarkable time. The card looks great. It exceeds my expectations. The little things the designer did in cropping, placement, etc. all stand out and make the card shine. I received my cards one day earlier than I was supposed to. When does that ever happen??? What a relief. I had a tough deadline and crazy circumstances. Thanks for pushing my order through and giving me such a great product. I am so pleased! Thanks again.
