The big mac has been around a while, as a matter of fact…this summer it celebrates 50 years. In honor of that they will be giving away FREE Big mac’s. Starting on the 2nd of August you’ll be able to pick up McDonalds currency that will allow you to buy one free Big Mac. Of course they will be collectable so do you use it to purchase a big mac OR do you keep that coin. See the coins and read more HERE!
