Thought this is worthy of its own post. Full credit goes to Bargainaholic for the find.
Update 21/09: Register and create a brand new Subcard account and you'll receive a free 6 inch sub and 390ml drink offer within 24 hours (was previously instant upon signing up)
Offer will become available within 24 hours of signing up to Subcard
Offer valid for 7 days from registration
Update - App isn't Required
Try these steps using the website as the app is very slow and glitchy at times.
- Register and sign up here
- Login on the next screen after setting your password
- Select the store you are ordering at
- Select the "Offers" tile
- Select "Open Offer" on the 'FREE Subway Six Inch sub & 390ml Coke' offer
- You can then either scan the QR code on that page at your selected store (make sure your screen brightness is turned up) or select "add to order". If you select "add to order" you then go back to the ordering menu section and add a 6 inch sub and 390ml drink for the discount to be applied.
For those wanting to use the app, try the above steps within the app. Just note the app can be slow and painful to use compared to using the website.
Note: When ordering online or via the app, at some stores the offer will come up with "offer not applied". If that is the case try a different store or use the QR code from the email containing the offer to scan in-store at the register.
