I saw this offer in the window at Subway at Concord NSW, and a couple of Sydney CBD stores as well. This offer is not available at every Subway, so just look for the poster or signage in the window or in the store.
Here is the deal (please see picture for full details, conditions, T&Cs, etc.)
$10 for any Tier 1 Footlong sub and Lipton Ice Tea
Subs included in this price range are Veggie Delight, Meatball, Turkey, Ham, Pizza, and Seafood Sensation.$11 for any Tier 2 Footlong sub and Lipton Ice Tea
Subs included in this price range are Tuna, B.M.T., Veggie Patty, Roast Beef, Turkey & Ham, and Subway Club.$13 for any Tier 3 Footlong sub and Lipton Ice Tea
Subs included in this price range are Roasted Chicken, Chicken Teriyaki, Steak & Cheese, Chicken Classic, Chicken Strips, and Subway Melt.
It is meant to be a Sydney-wide deal but some stores may choose not to participate. Basically, if the poster is visible, the offer is available :-)
I'll update the following list as comments come through that confirm which stores are running the offer.
Concord, Majors Bay Rd.
Druit St., CBD Sydney.
Park St., CBD Sydney.
Liverpool St., CBD Sydney (Crownanchor is certain that he/she saw the poster at the store).
Coward St, Mascot.
Im sure i saw this on a postervat Liverpool street store in Sydney CBD a few days ago.
