Best Buy stores in the U.S. surpassed the 600-store mark and the company opened its first global-sourcing office in Shanghai in 2003. In June, Best Buy divested itself of Musicland in a deal with Sun Capital Partners under which Sun Capital received all of Musicland's stock and debt. Best Buy launched its "Reward Zone" loyalty program in July following an 8-month test of the program in San Diego, California. Also in 2003, Best Buy's corporate offices were consolidated into a single campus in Richfield, Minnesota.
