thrift shops, I would never dream of buying new for my kid's wardrobe, to me it's a total waste of money. If I shop well and often at the thrift stores I can find good quality clothes for less money than the cheap clothes at the discount stores. It's even better than buying new for the oldest, then letting the youngest grow into it because they each have their own styles. Oldest likes jeans, warm shirts and sweaters, youngest likes sweat pants and T-shirts.
There's also a small store here, in a nearby small town, that's sort of like Jayhawks? It's called Sunbird, but I'm pretty sure there's only one of them. It's locally owned, but it's got REI type outdoor sporting goods, a hardware section and a fairly large Carhartt's type blue collar clothes like work boots and overalls. What I love about it is it also has basic sweats, jeans, and T-shirts in all (adult & kids) sizes with nothing on them but cute pictures... no logos, no Blues Clues or Scooby-Doos. I don't suppose you'd ever be in Yelm, but small towns tend to have those only-place-in-town / little-bit-of-everything stores, maybe there's something similar near you?
