If you join Arby's email list, you'll get a coupon for a free signature sandwich with any soft drink purchase. So buy a small drink and you'll get a free sandwich. Make weird bird noises at the people sitting next to you, causing them to leave before finishing their fries, and you've practically got a free meal!
Don't let the title fool you either. No Arby's employee will sign their John Hancock on your sandwich without your explicit request. That'd be weird.
The free sandwich coupon expires 7 days after you sign up.
Joining their email list will also get you the Arby's birthday freebie! As of 2018, it was still a free small shake with any other purchase. I sometimes forget whether or not I've posted this offer (turns out I have!) Some might say I'm forgetful. To them I'd say … wait, what are we talking about again? Who the heck are you? WHERE AM I?!?!
