The store sell gently used clothes and toys. They don't offer super high buy rates because they are a business trying to resell the clothes at affordable prices. IF you don't like it have a yard sale or something!
They girls are friendly and always seem busy. No one is just lolly-gagging around. They don't mind kids being kids while mom is shopping even allowing the little ones to explore the toys while mommy shops! When you have a question they are alway willing to help.
