I am a HUGE fan of Subway. So I was so excited when I saw this offer while I was on vacation!
Text your Subway Card Number to 35562. You will get 50 points added to your Subway Card on your next visit! And, 50 Points is enough for a Free 6 Inch! YAY!
So, it may have to be on your second trip to Subway, but you will end up getting your 6 inch Subway Sandwhich for Free!
