I read your post yesterday, but sometimes, people do not know the answer.
My child is now in college and back in the day, most consignment stores paid about the same. They were also very picky. You will be surprised by what they will not take and how little you will be paid.
To save you time, you could call the places closest to your home and just ask them how much they pay and what they are looking for. It will save you time. Nothing worse than driving all the way across town for $10.
Also consider putting the clothes on craigslist.com or have a short garage sale with a neighbor.. I usually do one every 6 months from 7:00am to 1:00 pm on a Saturday. I advertise on craigslist and donate whatever is left over.
Take a photo and give descriptions.. Then you set the price you think is fair.
