“The cards are wonderful and arrived quickly. I also was happy that the sayings are customizable. I will definitely be ordering from Greeting Card Universe again!”

“Every card I have received over the years is perfect. Absolutely beautiful. Was for a 1st Mother's Day. She absolutely loved it. Also added a photo collage inside. So well the money. Much better than store bought cards. This is the only way I will buy special cards now. Fast shipping.”
