Am I able to buy food from here as the local stores are running out of noodles & items that hold a long shelf life.

Three Square doesn't sell food. They are an organization that collects donated food items and work with partner agencies to provide food for at risk people. They provide food to local food banks as well as several children's and seniors programs. If you need food assistance their website has a list of local food banks that they work with.

Go to the food pantries. On Facebook search food pantries and on Google search for food pantries open each day
