Of course we immediately test drove this offer out. Indeed. when we texted 'curly' to 27297 we got a response asking for our zipcode to receive a free regular roast beef sandwich. We texted back our zipcode - however instead of the free sandwich we were informed to "show this text message to the counter staff at any Arby's and we would receive a free small shake. Free shakes are a good thing - but it seems Arby's cannot seem to deliver what they promise.
