Need help finding a youth sized "soft" shirt that is price conscious!

Hi, I'm doing the spirit wear for our elementary school and my vendor told me I could pick anything from San Mar... Well that has quite the selection and I can't see the prices. I chose the PC54Y to fill the need for the "cheap cotton shirt," but I'd also like a "soft" option while still remaining price conscious to our families. What would you recommend that comes in youth sizes?
