Game tickets, antique china, power tools, jewelry, laptops, cars, pianos--they're all available online, new or used, cheap or pricey. If you haven't learned the in's and out's of the online auction yet, this is a good time to start. With the holidays just around the corner, think of online auctions as another option for finding gifts, decorations, and those gotta-have's that always seem to pop up around this time of the year. Have a house bursting at the seams with too much good stuff already? Downsize online, and pick up a little cash to cover the holiday bills.
