DOLLAR TREE REPORTS FIRST-QUARTER SALES OF $975.0 MILLION

COMPARABLE-STORE SALES INCREASE OF 5.8%

CHESAPEAKE, Va. - May 10, 2007 - Dollar Tree Stores, Inc. (NASDAQ: DLTR), the nation’s largest $1.00 discount variety store chain, reported total sales for its fiscal first quarter of 2007 were $975.0 million, a 13.8% increase compared to $856.5 million in last year’s fiscal first quarter. Comparable-store sales for the quarter increased 5.8%.

“Although challenged by an earlier Easter selling season, our comparable-store sales momentum continued to build in the first quarter,” President and CEO Bob Sasser said. “The 5.8% comparable-store sales increase was on top of a 4.0% increase in comp-store sales for the same period last year. Sales gains were driven by improved in-stock on basic products and strong seasonal sales, particularly for Valentine’s Day and Easter.”
