If you can walk into a supermarket and find Costa Rican bananas, Brazilian coffee, and a bottle of South African wine, you're experiencing the impacts of international trade.
International trade allows countries to expand their markets and access goods and services that otherwise may not have been available domestically. As a result of international trade, the market is more competitive. This ultimately results in more competitive pricing and brings a cheaper product home to the consumer.
