Using Vistaprint could very likely lead to you being signed up to FAKE discount clubs and hundreds of dollars benig taken from you Visa/bank without your knowledge or permission.

I have a huge blog post with all the details of all of the different scamming sites Vistaprint and Adaptive Affinity run and how best to get a refund.

According to the Washington Post http://www.washingtonpost.com/wp-dyn/content/article/2006/05/06/AR2006050600160_pf.html this negative option selling scam earned the parent company Ventura $650 million in revenue in 2006.

If you have already used Vistaprint, start checking your bank statements.
