Shopper Testimonials
“Greeting Card Universe is just the BEST. I've ordered cards several times. What makes them so unique is the ability to add my own text to the cards, which is just wonderful for sending holiday and special occasion cards to friends and family with my own sentiments. Cards come very well packaged. We get 20 or so at a time. They arrive usually within 3 or 4 days of my order and are cello wrapped inside a sturdy box. I've always ordered glossy finish, which is just lovely. Paper is thick and envelopes are first rate and actually seal. I recommend them highly for anyone who wants to send a real card these days rather than an e-card.”
