Not only is McDonald’s Corp. saying it will spare customers an egg surcharge, it will also launch a one-day offer on the McMuffin sandwich for just $1.

The discount celebrates 50 years of breakfast menu items, and arrives as an avian flu crisis pushes US egg prices to record highs.

“Unlike others making news recently, you definitely won’t see McDonald’s USA issuing surcharges on eggs,” the company’s North American Chief Impact Officer Michael Gonda said in a post on LinkedIn.

The Egg McMuffin promotion provides some relief for budget-conscious Americans squeezed by an ongoing egg shortage. The move is in contrast to restaurant chains that have tacked on an additional cost for menu items that feature eggs. In recent weeks, both Denny’s Corp. and Waffle House introduced fees to their menus.

The McMuffin deal will be available to users of the McDonald’s app on March 2.
