The fast-food chain is urging loyal customers to take action of the current Subway Rewards scheme.
Customers have weeks left to use their points before Subway shakes up its rewards scheme.
Currently, Subway’s loyalty scheme allows customers to collect points by scanning their app or card at the till when making a purchase.
For every pound spent, foodies can receive 10 loyalty points, as long as it is registered on the app.
If the card is not registered customers only get five points for every £1 spent.
Diners can then save up points for free food, with 100 points needed to get a hot drink, 200 points for a snack, 500 points for a six-inch sub and 1,000 points for a 12-inch sandwich.
But the money-saving scheme is set to come to an end.
The Subway App and Subway Rewards card will become unusable from May 14 – with any points balance being unredeemable.
Posting in the Extreme Couponing and Bargains UK Facebook group, a bargain hunter shared the discovery.
The user said: “For anyone like me who doesn’t read emails from Subway, someone has just made me aware of the upcoming change.
“Make sure you claim your points whilst you can.”
Subway sent out an email to its customers informing them of the change, and some have been sharing the information on social media.
The email read: “We’re having a makeover, with a new levelling system, bigger rewards and surprise treats, the more you spend the better it gets.
“You have until May 14, 2024 to continue to make use of the current Subway Rewards benefits and offers.”
Fans are now being urged to log onto the Subway app, check their current points balance, and redeem them as soon as possible.
Many users who raced to redeem their points flocked to the comments section to share their thoughts and opinions.
One said: “I’ve got like three free Footlongs on my card.”
Another added: “Picked up my Footlong for free with 1,000 points on Thursday. It has been years since I’d been.
A third wrote: “I was shocked to see how many points I had after this email.”
A spokesperson for Subway said: “We value the loyalty of our guests and we’re excited that our new Subway Rewards programme will offer them a more personalised and unique loyalty experience.
“As points from our previous rewards system won’t transfer automatically, we want to ensure everyone has an opportunity to redeem their points.
“Therefore we encourage all our guests to enjoy their rewards ahead of our new programme launching on 15th May.”
It comes as the iconic fast food chain revealed it will be giving children their Subway’s Kids’ Meal for free when you buy any footlong sub.
The bargain offer includes a four-inch mini sub of ham, cheese, tuna, or Veggie Delite, and kids will also receive a drink.
