Connecticut Attorney General Richard Blumenthal accused the company in his lawsuit of a "bait-and-switch scheme" that he said treats "customers like suckers," ABC News reported.
The suit claims customers were lured into Best Buy stores by prices quoted on the company's Web site only to find the items at higher prices at the store.
The higher prices were found on a look-alike Web site available only in the store, the suit said. The issue came to light after a Hartford (Conn.) Courant columnist wrote of a man who found a laptop on BestBuy.com advertised for $729.99 but when he got to the store it was listed at $879.99
A company representative acknowledged the existence of the in-house site but denied that it was a ploy to overcharge customers, ABC News said.
