WASHINGTON — Wholesale businesses boosted inventories for the 14th consecutive month but sold fewer cars, pieces of furniture and petroleum products in February.

Sales at the wholesale level slipped 0.8 percent in February, the first setback since June 2010, the Commerce Department reported Friday.

Inventories rose 1 percent and have been rising for more than a year. The string of inventory gains pushed them to $438 billion, up 13.4 percent from the low reached in September 2009.

The drop in sales is likely temporary, given expectation for gains in consumer demand in coming months, supported by tax cuts and stronger employment growth.

Auto sales at the wholesale level dropped 2.2 percent, furniture sales fell 2.2 percent, and sales of petroleum products declined 1 percent.
