As you may have noticed, every once in a while we encourage you to engage in the act of shopping. And here’s a reason to do so with renewed fervor: Buy something on Gilt between now and Sunday and we’ll donate $1 to charity: water, a non-profit organization that provides clean and safe drinking water to people in developing countries. It’s the very definition of unimpeachable cause; and unless you’re a total Scrooge, this is the time of year you’re spending money anyway, right? We’re also sponsoring charity: water’s annual gala next Monday night, December 13, to be hosted—impeccably, we are certain—by Roger Sterling himself, John Slattery. V.I.P. tickets to the event, the proceeds of which benefit charity: water’s work, are still available here.
