Ebay

I am amazed at what people will bid on in an Ebay auction. My husband had currency left over from a trip to Europe that is obsolete because of the conversion to the Euro. He wanted to throw it away, but I told him we should but it out on Ebay hoping to get just a few dollars for it.... The last time I checked, the bidding was up to $18.
Getting stuff out on ebay and dealing with the shipping, etc can be a big pain, but it can pay off big sometimes.
