Costco Wholesale Corporation reported comp store sales for the four weeks and 13 weeks ended Nov. 29 rose 2% and 1% respectively in the United States. Excluding gas sales, U.S. comp sales were flat during the month and grew 2% during the 13 week period.
Rising gas prices and a falling dollar propelled dramatic growth internationally, where Costco's comps grew 21% for the four week and 14% for the 13-week period. Excluding those two factors, international comps would have grown just 7% in both periods. Costco operates 77 stores in Canada, 21 in the United Kingdom, seven in Korea, six in Taiwan, nine in Japan, 32 in Mexico and one in Australia.
