Is Craigslist really the only option? Or going to Once Upon a Child? I'm guessing that Once Upon a Child will probably only give less than $1 on most things? Or would I be better off just donating them and taking the tax deduction?
I use once upon a child. It's a rip off but similar to a garage sale without all the work. You might have good luck selling lots on e bay if its all name brand but that's too much work for me.
I buy by the bag/box on CL. Don't list per item, as that is a waste of everyone's time. Just take a photo of a bunch of it and list as: $40 - 20 pieces, size 6-12 months, brands: blah blah blah.
If that's too much trouble, consign or donate. Honestly, I'll probably give most of mine away when we're done with kids. I had a lot given to me and I'll pay that forward if I can find someone that wants them.
