Tiffany & Co. is determined to increase its stores in the United States, which currently count to 68. For this, it has strategised a new format of smaller stores which would be called Tiffany & Co. Collections, and the first such is scheduled to open in 2008.%%Tiffany CEO Michael Kowalski said that, " This new format has the potential to significantly accelerate U.S. sales growth over the medium- to long-term and enhance profitability due to a merchandise mix weighted with higher-margin products."%%The Tiffany & Co. Collections stores would retail a wide range of jewellery apart from engagement jewellery. With these new stores, Tiffany & Co. intends to increase its store numbers in the U.S. up to 170.
