Well, I guess it depends on what you have. For baby/toddler clothes, I priced them anywhere between $.50 (for one piece separates) to $5.00 (jackets, sweaters, etc.). Matched sets I would price anywhere from $2.00 to $3.50 depending on name brand and condition. Toys, I guess it would depend on the toy. We didn't sell a whole lot of toys since my kids still play with them. I did sell a ton of beanie babies at $2 each.
Also, things like strollers - liteweight $10, the sturdier strollers anywhere from $35 to $75. I had 3 Peg Perego strollers and a double stroller that I sold for $75 each, but again, they were top of the line and in excellent shape. I was told to sell stuff like this at a consignment shop, and I would have had I not gotten the price I was asking for. I wasn't going to negotiate these items. Other baby items I sold: exersaucer: $15; playpen - $40; high chair - $25; bassinet - $35; crib and dresser - $200.
Another money maker for me was kids videos - the Barneys and the Teletubbies and such that my kids had outgrown. I sold them for $2 each, and I wish I had more of them because they sold like hotcakes. Same with regular videos, if you have any of them. Hardcover books sold well, paperbacks not so good. Adult clothes aren't supposed to sell so well, but I sold alot of my stuff. It was hilarious because this one tiny woman came by and bought a ton of my size 10/12 clothes - she was probably a size 2! Who knows what she planned to do with them, because they would have been too big - and most definately too long. I sold my clothes anywhere from $2 to $10, depending on the shape and how in style they still were. I had a few pair of shoes that I sold - $5 each. DH and I were dying of laughter because this old woman, and I mean really, really old - like 80 or so, bought these boots from me - they were like biker boots, but with like a 3 inch heel. LOL, she was looking good!
I guess the most important thing I can tell you is if you think it won't sell, think again. Its amazing what people will buy. Price everything a bit higher than you might ordinarily, because people want to bargain. Its almost like its a game to them, they will fight with you over a quarter. Its a bit unnerving, especially if you are a person like me with very little patience for such games. In the end, it was worth it, it paid for a good bit of our vacation, but it was exhausting.
