Same-store sales at

Wal-Mart

(WMT) - Get Report

, the world's largest retailer, fell short of expectations last week, the company said Monday on its regular recorded call for investors.

Sales growth at both Wal-Mart and

Sam's Club

stores open at least a year fell below the company's 3% to 5% target. Same-store sales are forecast in that range for the quarter, though projections for November call for growth at the lower end of that range, the company said.

Wal-Mart said while its customer count was "sluggish" during the week, the average amount spent remained strong.

In October, Wal-Mart's same-store sales rose 4.9%. The company had planned for growth of between 4% and 6% for the month.

Wal-Mart shares closed Friday at $47.38.
