The offer is only valid today at participating US McDonald’s restaurant and to find out if your local chain is offering the deal, you need to download the McDonald’’s app to your phone and register an account. There, you can search which locations are celebrating National Egg McMuffin day, which will get you a free sandwich between the hours of 6am, and 10:30am. Why today for this new promo? McDonald’s says they’re offering free Egg McMuffins to help with its goal of increasing the app’s user base, but today also happens to be when Wendy’s rolls out their breakfast menu nationwide. “It’s more of a defensive move rather than an offensive move,” according to Morningstar analyst R.J. Hottovy, adding that McDonald’s wants their users to keep its breakfast at the “top of mind” since Wendy’s has spent nearly $80 million this year to promote their new breakfast menu. Wendy’s isn’t worried, though. Carl Lordeo, Wendy’s chief marketing officer, said the McDonald’s holiday “is the day that the Egg McMuffin and other old breakfasts are laid to rest. No longer will people have to suffer stale, tired, old sandwiches with folded eggs and microwaved bacon It doesn’t really matter why McDonald’s is offering a free Egg McMuffin, though. All that really matters is grabbing one for yourself because you’ve earned this. And that’s a good enough reason as any.
