Hi, I am a haunter by the name of Michael Carvajal. I bike to goodwill almost everyday to see if there is any gemmy or Simpsons item. I am not a gemmy collector, but I sell the items on ebay. I sell rare and common items, as well as rare non-gemmy items.

Be sure to check every once in a while, because you never know when ill find an ultra rare item!
