In what many are considering the holy grail of daily deals, LivingSocial is offering a voucher today for 50% off groceries at Whole Foods Market.

The voucher is good for $20 worth of merchandise for only $10.

They say beauty exists in the relationship between a “whole” organism and its parts. And with today’s deal, lettuce show you the natural simplicity of healthy goods, courtesy of Whole Foods Market: Pay $10 for $20 to spend on high-quality natural and organic products. Whether you want local produce; freshly prepared foods; gluten-free goodies; or you simply want to avoid artificial preservatives, colors, flavors, sweeteners, and hydrogenated fats, Whole Foods Market has you covered.

Whole Foods is donating 5% of the sale price to their brand new organization, the Whole Food Foundation. Their goal is to improve children’s nutrition through programs with school and parents.

Unfortunately, there is a limit of one voucher per person. But If you buy the voucher, share the deal using a special link, and 3 of your friends buy the voucher following your link, then yours ends up being free.

As of right now, over 269,000 people have bought the deal. Whole Foods is the first national grocer to offer a daily deal with either LivingSocial or Groupon.
