“They're EXCELLENT! The customization options are absolutely amazing! Adding photos to a greeting card was something I'd never though would be possible. As I've stated before, many local brick & mortar stores have either reduced or eliminated their greeting card sections. I would not have known about Greeting Card Universe if it weren't for your customer Linda Lober.”
