The story
Tom Holley owned the local Grandpa's chain in St. Louis, which he sold in November 1999 to Value City so he could open additional Deal$ stores after the first few proved successful. It eventually evolved into a chain of 41 discount dollar stores located from Missouri to Ohio. Later acquired by SuperValu on May 20, 2002, Deal$ had grown to 53 stores. And finally by March 29, 2006, Dollar Tree, Inc. acquired all Deal$ stores from SuperValu Inc, now 138 outlets.
On March 1, 2016, Dollar Tree converted most of the company's Deals stores into Dollar Tree stores. The conversion was done due to the parent company's acquisition of Family Dollar. The remaining 5 Deals stores were converted to Family Dollar stores.
Since 2018, some Dollar Tree stores previously known as Deals locations, many located in the Northern United States, closed down.
