Although swaptree has been in beta since 2004, it will finally launch next week on July 4. This service uses calculations that match you up with others based on that now widely known but little understood concept of algorithms. Before you run to the dictionary, it simply means that the service will narrow down items that are equal to those that you have and based on such results as location, objectively match them up. swaptree is free to the public, so you only need pay postage with Media Mail and a monthly fee of $1.00 to cover credit card transactions. Now might be the time to get into the back shelf of your closet and get rid all of those ugly ties that Uncle Peter keeps sending you for Christmas.
