I would research what stuffed animals you have and only list the big sellers. Most will not fetch that much unfortumately. List in/like new condition, comes from smoke free home, etc.
A side note/idea: I too had a ton of stuffed animals and my 2 kids get way too many so what I have actually been doing for 2 years now is I called our local You, Inc - a company that deals with children in need - you can also contact your local PD/FD, orphanage(s), social services and ask if they take donations - specify what you have to give. Most public service places will accept like new stuffed animals to present to young kids when they are...being adopted or put into foster care, have lost everything in a fire, my kids got one when I had them fingerprinted at the police station so they will accept things like that. I have also donated them to the childrens ward at our local hospital. Some of these agencies will also accept baby blankets and other items as well.
Good luck on ebay!!!
