On CAPS, 33% of the 262 members who have rated Vistaprint believe the stock will underperform the S&P 500 going forward. These bears include WombRaider and bfaulkner87.

About six weeks ago, WombRaider summed up the bear case with one simple business truth: "When you burn your customers, eventually it will bite you."

In a pitch from late last year, bfaulkner87 expands on that sentiment. Here's an excerpt:

Currently trading at about 40x p/e, which, despite the fact that the company is growing its top line quite well, is not going to produce a meaningful return for long-term investors. What's interesting is when you actually take a look at those earnings the price becomes even more ridiculous. ...

When you order from vistaprint.com after you fill out your credit card info there is a display button that says, "save $10." If you click on the link your credit card info is automatically sent to a third party, Vertrue Inc. and you're charged $14.95 every month without notice or receipt. ...

Vistaprint downplays the referral revenue's significance by comparing it to their revenue, not their net income. ... So the lofty 40x earnings actually becomes about 100x earnings less referral revenue at a 35% tax rate.
