On their facebook page, SUBWAY is offering a coupon whereby you can buy a Footlong Sub and 600ml drink, then get another footlong and 600ml drink of equal or lesser value for free. If you actually need more than one sub, this is going to work out cheaper than last weeks $7 sub deal. And the bonus is, you end up with 2 coke unleashed codes to redeem. :)
Conditions state that it is at participating stores only, and there were a few who posted on the $7 deal that their local store would not accept, so might be wise to check beforehand to avoid some frustration at the checkout.
(Sub prices vary, and I have no idea what they charge for a 600ml drink, so a price in the title a bit hard to do sorry)
To get to the voucher from their wall, click on the Subway Summer Deals tab on the left.
EDIT:
You can skip the whole facebook thing and go straight to the coupon on the subway page:
