I don't know what you could do Disney related. But I do ebay and I do quite well. I get my inventory from thrift stores, garage sales and my own kids closets. I buy new Gymboree outfits from the actual store on major sale, my kids look cute and wear them awhile and then I sell them on ebay for either the same amount I paid for them or many times for even more then I paid for them.
You just have to know what sells and what doesn't... I do mostly kids clothes, some adult clothes and a few other things if I know it sells well. I have the potential to bring in $1000 a month after paying for inventory and ebay/paypal fees. It's nice to earn my own money and not have to go out to work.
