I have had great luck with Craigslist on baby stuff. Never tried Ebay.
Just beware of the people who want the stuff, offer to send you a large cashier’s check to cash for them, keep a little extra for yourself and then want you to wire the rest of the money to them, in another country. The check will bounce and you’re screwed. I had several people email me with such an offer.
These wire scams are very common. Just state in your ad that it is a cash sale ONLY and ignore the ones who want to pay with cashier’s checks, etc. Cassie
