filing that first-quarter sales will be $740 million to $755 million. Dollar Tree's original sales guidance for the period was $770 million to $790 million.

The company blamed bad weather and "Easter falling in March this year" (although the company's quarter runs from Jan. 30 to April 30).

"The company experienced positive comparable-store sales results for the first nine weeks of the quarter, and while the quarter does not end until April 30, 2005, post-Easter selling has been lower than planned against the difficult comparisons to last year," it explained.
