vistaprint.com the world's largest online business card company.
Great printer but aggressive, bordering on fraudulent marketers.
As I was trying to checkout of an order, different dialogue boxes kept popping up with add'l offers. I closed them all, but apparently, without my knowledge I signed up for another business (run by vistaprint) to get coupons. My credit card was charged $14.95 per month for 4 months before I noticed. I had to call two companies to get the membership stopped and had to also close my credit card account.
Thanks, Vista Print! I will never use you again!
