This is my favorite place to sell my used baby/children's clothing. You get paid upfront, when you drop off the clothing. The owner goes through your items, picks what she wants to buy, and buys it from you. I have to add, she's super nice, too. I also love that you aren't required to iron your clothes before dropping off; you just have to launder them, and then lay flat in a clothes basket.
This store is always immaculate. It has a nice feeling, and everything looks so clean and well organized. I have never seen such a nice resale shop.
I haven't bought many clothes here, but they do get some great things. The shop owner is very particular about the condition of what she accepts, too, so you know that whatever you buy will be in excellent condition. The prices are great too. This is also a great place to buy toys! I have bought quite a few toys, and think that used is the best way to buy baby toys. They are used for such a short time...why pay retail?!
A side note...you do have to make appointments to bring your items in. Call ahead to book your appointment.
