Even during this economic downturn, certain luxuries can be attained at bargain prices-that is, if you’re willing to shop for them online during restricted hours. The Web-based upscale-home-accessories dealer One Kings Lane holds sales daily-usually representing one or two manufacturers per day-offering discounts of up to 70 percent off retail. Sales last for only 72 hours and who knows when any given company will be back to play again? Click on Sales Event Calendar to see whom they’ve got lined up. When we last checked, linens, pillows, and bath accessories from Dransfield & Ross were having their moment (a celadon-colored faux-crocodile-with-nailhead-trim tissue box, normally $80 retail, was sold out-it had been going for $39; some elaborate embroidered pillows that are normally $475 were available for $199). Coming up this week, selections from Arte Italica (see photo above) and Arteriors Home.
