$2 Shake with Any Double Burger Purchase at Smashburger Through September 30, 2019

Smashburger is running a limited-time deal where you can get a shake for $2 when you buy any Double Burger.

The promotion is good at participating locations through September 30, 2019 (except for September 18, 2019, when it's likely they will be running a different deal for National Cheeseburger Day).

A milkshake normally costs $5.99 at my nearest Smashburger restaurant while a Double Burger starts at $7.39.
