Spend your time building a real online income. That peanuts type stuff isn't worth the time. When I first started to make money online, for a $40 investment I had a $600 return in the first week. After I got better, I could turn $100 investment into $20k-$40k within a month. The risk is small and the rewards are great once you learn a few simple secrets. I don't use that method anymore because I'm lazy and don't feel like filling the couple thousand orders any more, since I can make $40k-$60k a year with basically no work on my part now.
Too many people think they're going to make big money being an afilliate or some such, and spend a lot of time and money trying to make them work. Right now I spend $40 a month for my business, half to the service I use, and half to an advertising outfit. I resell the service at $20/mo per person and I keep 100% of the profits. I average 200-250 customers that pay me every month. It's all automatic, I don't have to do anything, and the company I pay $20/mo to for the service provides all of the customer service to all of my customers. I just pay the second company $20/mo to advertise the service I offer.
In the past, I played with craigslist, and other online classified sites. It was free, and it did work, but once I found this advertising service, things really skyrocketed.
My point is just don't waste your time or efforts on the little stuff, put it into the bigger stuff with bigger long term rewards. I read somewhere that the average online business owner makes $50k-$60k per year. Get your slice of that pie.
