I used to get postcards from Vistaprint and more recently business cards. I like the photo business cards better than postcards because I can carry them with me all the time in my wallet and give them out when a conversation about my art comes up. Although postcards are great, you can't carry them in your purse without them getting dogeared.
I started using Vistaprint because of their "free" deals that are always advertised on the web, but I have become increasingly disgusted with their business practices. If you don't watch every pre-checked box on the multiple offer pages you have to click through to check out, you risk being signed up for a "club" that automatically takes the $50 membership free from your credit card account.
So after seeing my friend's mini moo cards I decided to try out www.moocards.com. Instead of making their money on seedy business practices, their business seems to be based on good design and quality cardstock. They also allow you to have several images printed in one box of business cards. So as you can see above I paid for one box, but I made three designs. I just made my designs in photoshop using their template in a layer to make sure the bleed was right, and then uploaded the .jpg.
I'm really happy with the quality of the cards/cardstock and definitely would recommended them. They may be more expensive than places like Vistaprint, but they seem to be committed to the product rather than the con. They also have a first time customer deal : http://moo.com/share/b8yqqc
If anyone wants one of new business cards - just send me an email at firstname.lastname@example.org and I will pop one in the mail. If you want a specific design from above let me know or I will pick one randomly.
