I know I've read somewhere on here about including your business card or something when you send in payments for bills. I recently sold some books on ebay and was thinking about including my information with the books that I ship. What would you send? Just a business card? Some type of flyer? Or a coupon of some sort to use on PC purchases? I have three books that I'm shipping to different parts of the country....if I could find increased business this way I'd love it. Please don't misunderstand...I'm not selling anything PC on ebay or even considering it. I'm just looking for ways to increase business. What do you think? Thanks!
