The Yankee Candle shop, located in the Prudential Center, is a treat for the olfactory system. This Massachusetts-based company is the largest manufacturer of scented candles in the country. The delightful assortment here, including seasonal favorites and rare novelties, is almost overwhelming. The large candle jars are the most popular item, and they come in dozens of scents, including new assortments like spiced orange, maple pancake and apple pie. This store also sells its trademark "Good Air" odor-elimination products, as well as aromatherapy kits and other specialized air fresheners.
