Ours are done by size, though there's a lot that are in the wrong section. The one closest to our house (not Good Will!) doesn't have a changing room. We really don't care to go there!
I do alot of our shopping at Kohls, TJ Maxx, and Ross. I get that at really good prices and they hold up much better than Walmart.
I shop at Ross a lot. For some reason their shoes are not cheaper. I also like to shop at Academy's clearance for the boys clothes. I got nice name brand shirts on clearance this summer for $3 each at Academy's.
Thanks for the info. on Plato's Closet. I've never heard of one. Of course with the closest one being nearly 8 hours away, I guess it doesn't really matter
