Trepp LLC, which bills itself as "a leading provider of data, analytics and technology solutions to the global securities and investment management industries" and provides a steady dose of commercial real estate information to boot, reports that the oldest department store in England is closing, with owners blaming the retail tidal wave of e-commerce and higher expenses, a theme familiar to U.S. stores turtled by changing consumer habits. Bennetts department store opened as an "ironmonger" — a supplier of consumer goods — in 1734 in the city of Derby.
