Sonic Drive-In offers $1 Double Sonic Smasher Burger for first one million customers

The savings are getting juicy for burger lovers at Sonic Drive-In!

The popular quick-service restaurant just introduced its new Double Sonic Smasher Burger with two Angus beef, seasoned patties smashed and seared — crispy on the edges and juicy in the middle. It’s then layered with two slices of American cheese, Smasher sauce, crinkle-cut pickles, diced onions and served on a soft potato bun.

The new burger sells for $7.49. However, hungry bargain hunters can bite into one at a juicy discount. Regular price may vary by location.

From April 21 to 27, 2025, Sonic Drive-In is offering the Double Sonic Smasher Burger for just $1 at participating locations. The discount is definitely meaty at 87% off the regular price.

The discount applies to the first one million customers who purchase a Double Sonic Smasher Burger via the restaurant’s app. Find the bargain burger under “Deals”. Limit one per person. 

The offer ends April 27 or when one million redemptions have been made, whichever occurs first.
