Possible Cheap Eats at Subway?

I'm not a huge proponent of eating out, as I think you can eat cheaper at home, but I can't pass up sharing a good deal either...
Starting July 4th for customer appreciation month, it is rumored that Subway will be offering a 6 inch sub (Meatball Marinara, Cold Cut Combo, or Veggie Delite) for $2. (Now remember sales AND coupons!!!)
I just got my Twin Cities Clipper (we're in "Zone K") and found a coupon for a free 6" with the purchase of a 6" and a medium drink at the Mendota Heights location. (Here's a printable Mendota Heights.) The Subway in Crystal Center has a coupon for $0.50 off a 6" sub. (Here's a printable for that one Crystal Center.)

I'm not sure they will accept both offers, so let me know when the 4th rolls around if they will accept it or not...
