Do you have a Goodwill or a thrift store near you? They are a really great place to get deals. That is where I get my 3 boys clothes (ages 6, 2, & 9 months). They usually have sales a lot, too. The Goodwill’s in TN have a daily special and occasionaly a 50% off day. I find great clothes and most are name brands. Make sure you look over the clothes because every now and then one will have a tear or stain.
Also, have you tried asking for clothes on Freecycle? I do that to especially when I need something. Hope this gives you some ideas.
