Scottsdale, Ariz. - August 19, 2003 - JDA® Software Group Inc. announced that $2.3 billion Dollar Tree Stores, Inc., the U.S.' largest $1.00 discount variety store chain, is using JDA Portfolio® Advanced Store Replenishment by E3(tm) ("Store Replenishment") software to support select stores following a 60-day pilot implementation. The long-time JDA client plans to rollout Store Replenishment throughout its chain of more than 2,440 stores in 47 states to further optimize its in-stock position and service levels while reducing its inventory investment. According to Ray Hamilton, Dollar Tree's chief information officer, the Virginia-based retailer already relied on Advanced Warehouse Replenishment by E3(tm) for computer assisted ordering at its distribution centers so the next logical step was to introduce advanced replenishment at its stores.
