I tried their app to get a BOGO deal about a month ago. It did not work due to the app being glitchy. It was a waste of time. I ended up deleting the app. Never again.

To maximize these frequent Smashburger deals, buy $25GC in store, get $10 smash cash, thru 6/22 at participating locations. It's like another 40% off…

One of the terms for using the $10 "coupon" as they call it in Legalese is:

Promotion and Coupon cannot be used in conjunction with any other offer, promotion, or discount.

Which means you can only pay for full price items with the $10 you get when you buy $25 gc. To me, that is a lower value, more to the tune of $5 or 20% extra. Sam's and Costco sell 20% smashburger gc fyi. And couple of times in a year, they give additional $10 off, making it true $69.99 for $100 value that you can combine with promotions, offers and more.

What? That's $10 minimum in gas just to save $4 on a mid burger! If Chilis is within that 25 min radius you'd be much better off getting their 3 for me.

25 minutes round trip? Soft maybe. 25 minutes each way? Hard no. Nearly an hour to save 3 bucks? I hope your time is worth more than that.
And that's before we even consider the gas cost.
