I have tried going in this store multiple times, and I just don't get it. It seems that the prices are determined by the staff, and Avalon accepts only certain kinds of clothing. But these clothes are usually worn and in awful condition. I have seen a few cute things, but they often have holes or are just too old.
I agree with the others that the staff leaves much to be desired. They tend to be nicer to me when I come in directly after yoga or dressed up. So they definitely judge you when you walk in the door. This wouldn't bother me if the selection was really great, though!
I have much better luck at the Goodwill in South Side. The clothes are in better condition and usually cuter. Not impressed.
