Shopper Testimonials
“These recovery cards are perfect and I will send one for every month!”
Sandra - posted 3 days ago
“I LOVE your cards, and so do my family and friends. It is great to be able to personalize them, and to change font size, etc. for recipients who are vision impaired. The service is prompt (most of my orders arrive within three days), the artwork and designs are professional, and the prices (with discounts) are far superior to cards available in the stores in my area. I have recommended Greeting Card Universe to many people and will continue to do so.”
