Walnut Creek, Calif. Longs Drug Stores Corp. said Thursday that its same-store sales dipped in August.
For the four weeks ended Aug. 28, same-store sales decreased 1.4%.
Longs estimated that the preliminary August pharmacy same-store sales were hurt by recent generic introductions being substituted for higher-priced brand-name drugs, as well as some drugs becoming available over the counter.
Last month, CVS Caremark Corp. offered $2.7 billion to buy Longs.
