Domestic sourcing is when you buy products or services from companies or people close to where you live. It means you are buying things that were made, grown, or otherwise found in the same country where you live. For example, if you live in the USA, you might choose to buy apples that were grown in the USA rather than buying apples grown in another country. Domestic sourcing is important because it helps support businesses and people who are close to you and helps make your country's economy stronger.
