Do not go cheap when buying business cards.
When I opened my account for my business the bank teller told that certain business owners will check the feel of your business card. They can gauge the money you have by the material. This was my first business card. It was the cheapest one side card I could make. It will probably leave a bad impression. Another reason for a bad impression is that it is a plain white card with no branding colors.
