Let’s get smashed. Okay, not that way — but with Smashburger’s new online Burger Smasher Challenge. How many burgers can you smash in 30 seconds? (Secret: Everyone wins.) Once you’re done smashing, you’ll be rewarded with a coupon for a FREE side (up to a $2.99 value) with the purchase of an entrée. The coupon expires November 15. However, we don’t know how long the challenge is available for play — so start smashin’. With restaurants nationwide, click here for locations.
