Dollar Tree announced last month that it will sell 330 stores to private equity firm Sycamore Partners, which will operate the stores under the Dollar Express banner. Dollar Express was a Philadelphia-based company that was acquired by Dollar Tree in 2000.

The sale addresses regulatory concerns brought about by the planned merger between Dollar Tree and Family Dollar. The combined Dollar Tree – Family Dollar company will consist of approximately 13,000 stores and create the largest retailer in the dollar store sector.
