CORRECTED - UPDATE 1-Walgreen 2nd-quarter profit down on charges

* EPS 65 cents including charges, down from year-ago 69 cts * Restructuring charges were 4 cents a share * Shares up 5 percent (Corrects last paragraph to show stock moved up)

CHICAGO, March 23 (Reuters) - Walgreen Co (WAG.N) posted a lower quarterly profit as the company spent more to promote nonprescription items amid the weak economy while also taking charges for a restructuring aimed at saving money long-term.

The company also saw sales and earnings pressured because 2009 had one less day in the quarter than 2008, which was a leap year.

Walgreen posted second-quarter profit of $640 million, or 65 cents per share, in the fiscal second quarter that ended Feb. 28, compared with a profit of $686 million, or 69 cents per share, a year earlier.

In the past, drugstores could typically charge more than chains such as Wal-Mart Stores Inc (WMT.N) because customers were looking for convenience, not value. Now Walgreen and its rivals are selling their own lower-priced brands and putting more items on sale to keep shoppers coming back during the recession.
