Once I started churning credit cards in order to reduce my expenses and maximize the money I was getting back from my everyday purchases, I started following a lot of blogs and forums related to the subject. To my surprise, I was able to find a few of these opportunities pretty quickly and after double checking my math, I made the purchases. Since the sell prices are known going in and change rather infrequently, the risk I am taking on is relatively low. For the time being, deciding whether or not this business is worth pursuing long-term is still an open question. Fortunately, the start-up cost of this business is next to nothing and I could stop buying tomorrow, sell the rest of my inventory over the next couple of weeks, and walk away completely still having made a little money in the process. Will I still be doing this 6 months or a year from now? Making the operation more efficient is my main goal at this point, but at some point in the future I will take a close look at the time...
