Sofa for sale

I did not find any blip today. Came home late from the office and took a quick look in to the garage to find something. There was the sofa. We bought it last December, but discovered it was to big for the entrance to the room it was meant for. Tried to return it to the furniture shop but was rejected. We have tried to sell it but no response. Brand new sofa - completely unused - not even been in the room it was meant for. No way. We have tried to give it for free to the Salvation Army. They have more sofas than they are able to store. Our sofa is now wrapped in plastics and stored in our garage. The bags on the roof of the small Smart car are filled with pillows for the sofa. We have given up our attempt to sell it, but we must get rid of it. The question is how? It is not brand new any more - from Dec last year, but still unused.
