Most of you are probably familiar with Living Social, they offer a new deal each day to their members. Well today they’ve put out the largest national fast food daily deal – ever. The deal is a $13 voucher booklet, redeemable for five individual Big Macs and five individual large french fries. Snagging this deal will net you a savings of 50%.

According to Teter Sterling, Vice President of Marketing for McDonald’s, “Both LivingSocial members and McDonald’s customers are looking for delicious food at a great value, and this deal hits the sweet spot for both personal purchases and holiday gifts.”

At the time of this writing 67,557 of the voucher booklets had been sold. If you do the math, thats 337,785 Big Macs. That’s a lot of special sauce McDonald’s will be slinging around this holiday season.

A little FYI: each Big Mac contains 580 calories, couple that with large fries, you’re looking at 1,150 calories.

As I’m sure you can imagine, McDonald’s began receiving flak on Twitter questioning their quality of meat… you know, the usually. It got so bad that McDonald’s tweeted out the following, in attempt to stop some of the negativity:

It should be noted that purchasers of the deal will receive individual vouchers for each item, not one big voucher. So you won’t have to order the 5 Big macs & 5 large fries at one time… though we’re sure some of you will, I can see a Tumblr account coming out of this.
