This holiday season, you can snag 10 percent off a Raleigh bicycle at Bespoke bicycles in Fort Greene, 20 percent off anything at the Hom Store (cozy nesting gear) in Bay Ridge, or 20 percent off all hardcovers at Bergen Street comics in Park Slope. Those are a few of the deals available around Brooklyn courtesy of the Shop Brooklyn initiative put together by borough president Marty Markowitz. The point, of course, is to get Brooklynites buying locally this year and keep those storefronts filled with something other than “for rent” signs. We love this because it’s been a bruising year for the little guys, who add so much more to our collective quality of life than those few bucks saved by shopping at Amazon. Through Christmas, you can find all the participating stores, cafés, grocers and spas on ishopbrooklyn.com (officially launching Friday, but there’s a “preview” site up now), or look for the “Shop Brooklyn” logo in store windows. If all else fails, just try haggling. You’d be surprised.
