I opted out of all their emails and what do they do? Send me an email telling me not to opt out. Then they sent me an email telling me I abandoned my cart. Yes, I did, because by the time I got there they'd added so many BS fees that it was much cheaper to get my biz cards through someone else.
There are much better websites to get business cards from. I suppose if you want a few crappy, free cards then they're fine. But if you want professional cards, pay for it and use someone else.
