LivingSocial scores with Whole Foods deal

(CBS) - At 5 a.m. EST Tuesday morning, LivingSocial launched what was thought to be just another daily deal. Halfway through the day, however, it was clear that this offer was going viral.

Today's deal, which is still available as of this writing, is $20 to spend on groceries for $10 at Whole Foods Market. Similar to the Gap deal that put Groupon on the map (a 50-percent-off discount at a national chain) the offer is attractive to mainstream consumers that wouldn't typically buy from LivingSocial. 

According to USA Today, "LivingSocial said it was selling roughly 115,000 an hour, which company spokesman Andrew Weinstein said is its fastest-selling offer ever. That's about 30 deals sold per second."

It's an enormous win for the daily deals site, whose biggest competitor is Groupon.

The offer is said to sell out at 1 million purchases. There are currently 865,972 purchases made, so click away and get those veggies.
