Don't let the title fool you – Arby's will give you a free roast beef sandwich with a purchase of a drink, not just a pile of roast beef. That would just be weird.
Signing up for this offer will also get you the Arby's birthday freebie, which I sometimes forget whether or not I've posted (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?!?!
