Maximise your drink value and avoid hidden order fees with insights from BudgetFitter’s food editors:

• Present Student ID for 10% Off: Many UK high street branches offer a 10% student discount at the till upon presenting valid university ID.
• Collect Digital Loyalty App Stamps: Scan the official T4 UK mobile loyalty app at the till with every handcrafted beverage to earn stamps and unlock a free regular drink on your 10th visit.
• Opt for In-Store Pickup Over Aggregators: Purchasing drinks directly in-store avoids the £1.00–£1.50 third-party markup charged on food delivery platforms and ensures pearls remain warm and soft.
