I used them as well for my business cards which I got for free. I also get a ton of emails from them, some of which have really good deals.
im in the same boat as you. i even paid more to get like a thousand business cards, and now after parting ways with my partner, the name just doesnt quite fit (D&B Detail). i've been blacking out his name and phone number with a sharpie.
VistaPrint is who I have been going with for years. They always have specials going on and you can always Google for their coupons.
Just out of curiousity, is there a way to search and find out if anyone else is using the same business name as you have, or want to use?
