What a wonderful idea! About the same price as regular cards but becomes cheaper the longer you use the card and much more green.
Also feeling very grateful I went with Tapzo and not regular paper business cards as I was planning to. I just got a new phone number which means I can add that number instantly to my details with no problem. Where if I went with regular cards, that would have meant another order and a bunch of cards in the bin.
Look at me being green, ha!
