If the goal is to just get rid of it sell it cheap. Last time I had a garage sale I sold all my kids' clothes for 25¢. Sets I sold for 50¢. Clothes that were never worn or looked like they were never worn I sold for $1. I think I priced winter coats at $5 and didn't sell a single one. Shoes I sold for $1 if they looked brand new or 50¢ unless they looked really worn. I didn't make a lot of money, but things sure cleared out. Surprisingly I even sold socks and underwear. I had a box of each that I put out but didn't expect to sell. Two ladies who run a daycare talked me into selling them both boxes for $5. I think I had it priced as 5 for 25¢.
I bought colored dots that I put on items that were specially priced. You can find some that are pre-printed with prices, but I did like some thrift shops do and put up a poster that showed what each color dot cost. I didn't put the dots on the things for a quarter.
I had signs up that said "all clothing 25¢ unless marked." Things priced for more than a quarter I tried to hang up so it was obvious what was priced for more. Most of those things didn't sell.
Everything that didn't sell went to one of two places: a missions trip to an Indian Reservation or Goodwill. I had planned to take unsold items to a kids' consignment shop, but they would only take certain brands and I could only get store credit, not cash. I had looked at clothing there a couple of times and wasn't too impressed so I wasn't interested in store credit.
