sale. Find things around the house that you no longer need. Not only will
you build feedback, but your cash flow is high since you aren't having to

listing templates and establish a solid method to stay on top of your
auction sales and customers. Once you have things down, you also can
reinvest your income in items that you think might be profitable.
