We thought we’d help out the old guy with exclusive deals from some of our favorite shops and restaurants through December 14 (just show a copy of this e-mail). SHOP Tons of Old City boutiques are offering discounts, so don’t be shy. A few of the best: Sugarcube (25 percent off sweaters and outerwear), Art in the Age (20 percent off select men’s and women’s apparel and a free ecotote with $100 purchase), J. Karma (15 percent off regularly priced merch and a free gift with a handbag purchase).
