Vista Print has great sales on business cards and marketing materials. I've been using them for a couple years now, quite happily, until I just discovered they've been billing my credit card $14.95 a month for some sort of "rewards" program. On my budget, I would never have knowingly opted in for such a thing. It must have been one of those obscure check boxes that you have to uncheck in order to opt out, otherwise you're automatically enrolled.

If you use Vista Print, check your credit card statements to make sure they're not billing you without your permission too. Obviously, I won't be using their services again.
