“I love Greeting Card Universe! The cards are beautiful & the fact that you can personalize them is a real plus! Now I'm ready for any occasion & don't have to rush out to the store in pouring rain to buy a card at the last minute. Thank you!”

“I've purchased several cards from Greeting Card Universe and am very happy with them. You can choose your card and then make it your own by changing things on it. Makes it very personalized for whom you are sending it to.”
