Starting Sept. 8, McDonald's will offer Extra Value Meals, which combine select entrées like a Big Mac, an Egg McMuffin or a McCrispy sandwich with medium fries or hash browns and a drink. Prices will vary by location, but McDonald's said Extra Value Meals will cost 15% less than ordering each of those items separately. To kick off the promotion, McDonald's will offer an $8 Big Mac meal or a $5 Sausage McMuffin meal for a limited time in most of the country. Customers in California, Alaska, Hawaii and Guam will have to pay $1 more for those meals.
