I dont know if you are looking for new or used clothes but I dont ever buy my kids clothes brand new (they grow to fast to but brand new clothes:() I go to the unique thrift store... The store is huge and you can pretty much find what you need at I think really reasonable prices.
You have to look through sometimes but i garentee you will find what you need..
I know that there is one in golden valley but im sure there is more than one. You just have to look it up in the phone book..
Hope I helped a little:)
