No surprise to me. I worked in a charity shop years ago and it was the same then. It's the same on boot sales with them too. I had one woman tell me "one child, five pounds less". I said "two children, ten pounds more". She paid what I was asking, but didn't like it. I think my eldest son growling at my side didn't help. He was only about 15, but wasn't a little flower, if you get my meaning.
