If you don't need money, I would try thredup.com. They send you priority mail boxes, you stuff them, and list them on the thred up site. It's very easy. You don't get $ for them, but you are allowed to order boxes from other moms on the site. You pay $5 + shipping (it runs $10.50 I think for the shipping) I have gotten rid of many clothes that were cluttering up the house and have received some really cute things for my girls. (They also have a box of toys category) I HATE having a yard sale and this is so much easier. I can do it at my own pace, it doesn't cost anything, unless i order a box, and its kind of fun. They have some other perks, but I'm not trying to advertise. I just heard about it recently and joined last month.
I've bought things on craigslist, but I bought a lot of 12m girls clothes for $75, but it was a 30 gallon bag stuffed full including shoes. Even if you do it on Ebay, I would do it as a lot. I wouldn't want to pay shipping on indiviual items if I needed/wanted more than one. Of course, I have twins and always need ' more than one'. :)
