“I love Greeting Card Universe.They have great cards. I receive them in a timely manner as well!”
Mary Ann Venn-Parillo - Sep 28th, 2025
“First time ordering. Pleasantly surprised because the cards were heavier stock than I anticipated. Colors were great and so was the price. I will definitely order again and will spread the word.”
