Which sample sale / daily deal websites do you like?

With the new year underway, I'm sure many have made "saving money" as a resolution. Perhaps you've vowed to do you own manicures, cut back on cabs, stop sending out your laundry, or to become an "extreme couponer" (ok, not let's be real, not the latter). Can sample sale / daily deal websites help or hurt this resolution? Which are your favorite and how many of the deals you have purchased have you actually used?

I just counted and below is the full list of all the ones that spam me every morning! I would LOVE for someone to make some sense of which ones are worth keeping/reading and which ones I should skip.

Luxury retail: Gilt, beyond the rack, rue la la, ideeli

Home furnishings: onekingslane, rednook

Groupon-esque: Groupon, livingsocial, lifebooker, bloomspot, homerun, kgb deals, eversave, tippr, plum district, google offers, daily candy deals, urbandaddy perks

Travel: jetsetter, sniqueaway, voyage prive
