We love Tree House. They are very picky about what they take, so it's easy to find good quality clothing.
Once you learn the "rules" (nothing wrinkled, only in style, no scuffed shoes, 10 items at a time, etc.) consigning is a snap.
My kids drawers and closets are overflowing with Gap, Gymboree, Hanna Andersen, etc. I can say yes to something that I normally wouldn't waste my money on, for example a hot pink Barbie swimsuit, because it's only $2!
They are also a great place for dance items, Girl Scouts and dress up. We got a gorgeous dress for my daughter for $40--brand new.
There are toys for kids to play with when they go, too.
