Costco Wholesale Corporation reported net sales of $6.78 billion for the month of November, the four weeks ended Nov. 28, 2010, an increase of 12% from $6.04 billion during the similar period last year. This year's four-week period included sales from the company's Mexico joint venture, as the company began consolidating its Mexico operations on a prospective basis beginning with its 2011 fiscal year (on August 30, 2010); without those sales the increase would have been 9%.


For the 13 weeks of its reporting period ended Nov. 28, 2010, the company reported net sales of $20.6 billion, an increase of 11% from $18.57 billion during the similar period last year; excluding Mexico sales, the increase would have been eight percent.


Comparable sales for the four-week and thirteen-week periods ended Nov. 28, 2010, including Mexico operations for last year and this year, were as follows:
