Have used them several times... they make it easy to send clothing in, so that's a plus. My first bag had sent an unworn very expensive evening cashmere sweater from Neiman Marcus which they rejected which made me question what the criteria is for choosing items.
I have gotten some very good deals that I'm pleased with but cannot help thinking when I'm browsing lately that their prices are way too high... these are recycled used (some new of course) clothing that I could go to my local store and find on sale for about these same prices or less. The real bargain here is when they had their $1 sale... now THAT was fun and scored some good clothing.
