How or Where to sell a comforter?

Ok so I recently bought a comforter and I slept with it once but I dry cleaned it and it's in the original packaging. I bought it at walmart but I don't have the reciept and it doesn't go with my new room theme so I was wondering if there is some kinda a place where I could sell and get like $20 for it cause I bought it for $40 and it comes with pillow cases, bedskirt, ect. It's very pretty! Do you think I could sell it on craigslist or something if so what would it go under? Like furniture?
