New York - Retailers have released their final round of holiday promotions as the clock ticks closer to Christmas.

Best Buy is halfway through a Santa Sales event running in-store through Friday, in-store and online through Saturday that includes such deals as  a 46-inch Panasonic plasma TV and 50-inch Insignia plasma both priced at $550, and an Insignia Web-capable Blu-ray Disc player for $75.

The chain will also extend store hours on Sunday and will offer free online shipping on hundreds of thousands of items on Dec. 26-27.

Meanwhile, New York's J&R Music & Computer World has unleashed a torrent of last-minute sales, including a 40-inch Toshiba 1080p LCD-TV for $450 and a Panasonic 14.1MP Lumix digital camera for $170.

Whether it was the sale or J&R's close proximity to City Hall that lured him, New York Mayor Michael Bloomberg was among the throng of last-minute shoppers today who crowded the Lower Manhattan store.
