The East End's go-to surf shop isn't quaint or retro—quite simply, it's got the goods. That means polarized sunglasses by Oakley and Maui Jim, racks of wet suits and sporty swim trunks, and Freestyle and Rip Curl watches. Air and Speed may be the first choice of pros like Kelly Slater when they're in the area, but the shop caters to all ability levels and even to non-surfers. (Some customers just swing by for a gander and some sunblock.) Buying a board will set you back from $550 to $1,200; rentals are also available of soft-top longboards, epoxy short boards, and stand-up paddleboards—as well as Electra beach cruisers, in case you feel like riding something that's not a wave.—Darrell Hartman

Open daily 9 am to 6 pm, high season; 10 am to 4 pm, off-season.

The Hamptons (especially Sag Harbor and Hampton Bays) are renowned for top-notch antiques outlets, and with good reason. You'll find everything from museum-quality heirlooms to 1950s ephemera to midcentury furniture. The standouts include Good Ground Antique Center, where you can pick up costume jewelry and vintage patio furniture for a song, and Jed, which specializes in theatrical and expensive chinoiserie-inflected designs, such as an elegant ebonized bamboo mirror and midcentury modern finds like an upholstered Robsjohn-Gibbings chaise. The ultimate resource, however, is East Hampton Yard Sale, where proprietor Vincent Manzo's curated mix of well-priced objects (garden statuary, lamp fixtures, vintage posters, and more) comes with plenty of local gossip. The Hamptons also regularly hosts antiques sales, including the annual Historic Mulford Farm Antiques Show & Sale in East Hampton.—Updated by Darrell Hartman

To supply this home-design store at the far end of Southampton's Main Street retail drag, proprietor John Heilmann relies on his terrific eye and spot-on sensibility. Driftwood candelabra, coral candlesticks, sea grass rugs, and antique bookends carved into the shape of dachshunds and Boston terriers are just some of the trappings of the genteel seaside life sold here. Further temptations include Molton Brown scented candles, striped Sunbrella pillows, nickel-glass hurricane lamps, and quartz salt and pepper shakers. Even the briefest browse around this boutique will make you want to snap up one of the chic waxed duffel bags Heilmann sells and fill it with desirable loot.—Updated by Darrell Hartman

Open daily 11 am to 5 pm.

Searching for a set of bamboo-and-cotton sheets, spiked olives, or gingersnap cookies? This modern take on a general store in Sag Harbor is your one-stop shop. Among the gifts and essential items for the stylish Hamptons home, you'll find placemats in rainbow colors, Tea Forté teas, nautical-knot doorstops, patchouli bath oils, jauntily striped pajamas, and confections ranging from Marie Belle and Michel Cluizel chocolates to plump sour-cherry oatmeal cookies. Grab a coffee at the long counter and create a temporary masterpiece on one of the Etch A Sketches. A second outpost (with a similarly eclectic but more home-oriented selection) is located in Amagansett.—Updated by Darrell Hartman
