In a world without houses, all meals would be alfresco and people would sleep beneath the stars, accompanied only by the lonesome howls of roving loveseats. Adopt domesticated adornments with today's Groupon: for $35, you get $75 worth of housewares and home-décor items from RedNook.

RedNook fills homes with décor, furniture, and accessories marked below retail value, leaving members surrounded by hand-painted accents and goods that hint at futuristic design with adventurous color schemes. After signing up for a free membership, customers gain access to 72-hour online sales events that feature colorful dishes, elegant lighting, and furniture items designed by imaginative manufacturers and up-and-coming artists. RedNook's past events have stocked domiciles with kitchen supplies by Tru Bamboo, which shapes sustainable serving sets ($20) and cutting boards ($22) that naturally repel bacteria and attract helpful pandas. The constantly changing selection of housewares has also showcased the kaleidoscopic polygons and fleurs-de-lis of area rugs by Le New ($27+) as well as hand-powered food processors by Fissler Finecut ($37), which quicken cooking projects like a map of the crème-brûlée genome.
