On Thursday, the Washington based largest membership warehouse club, Costco Wholesale Corp. reported a 5 percent rise in comparable store sales figure for October, and consequently a rise has been reported for the year on year sales by 7% to $5.68 billion from $5.3 billion in the year-earlier month.

The strength of the dollar led to weak sales, higher employee benefit costs and lower foreign earnings, which adversely affected the Costco Wholesale Corp.'s fiscal fourth-quarter earnings as it declined 6%. 

The fiscal third-quarter earnings of the warehouse and discount retailer Costco Wholesale Corp plunged 29 percent, chiefly because of lower revenue, a $34 million litigation payment, and increased staff-benefit costs.
