Just completed an experimental marketing campaign and thought I would share. I didn't make a ton of money but for the work i put in (almost non) I'm pretty happy with the results. I created a one page sales letter selling an ebook how to sqeeze extra miles out of your gas tank 10 secrets etc. I printed up a couple hundred business cards with the URL and such and left small stack of them on the counter next to the cashier window whenever I went to the gas station for gas, soda, cigs. (I drive alot for my day job) I did this for about a month. I made about $200 selling the book online for 9.99. When making the ebook, I just gathered the plethora of info from the web and found pictures to pretty it up. Used MS Paint to draw arrows and circle to certain car parts. Total of about 32 pages. Took 2 hours to make including biz cards. I'm not counting the time to pass out the cards cuz I was there paying for gas and stuff anyway. so $100 an hour is satisfying. I think I'm going to print out some more cards.
