Shopper Testimonials
“Always pleased with the selection & service.”
Debbie - Dec 2nd, 2021
“I can't believe my luck in finding this site to buy my cards. I am one of those persons who stands in front of the card display in stores and reads, reads and reads the cards until I find just the right one for the person I'm buying the card for. With Greeting Card Universe I can choose their words, subtract or add my own to say just what's in my heart. I can add the recipient's name and a photo I choose to make it very personal. Not to mention the price of the cards, they are more reasonable by far than the stores. Just this morning I showed my sister over FaceTime a few of the cards with a recommendation to give them a try. It didn't take much convincing! I couldn't be more pleased.”
