A TikTok user has revealed how Tesco shoppers can get a ‘free lunch’ alongside a Costa coffee at the popular supermarket.

@passwithbecky has gone viral on the video sharing platform after explaining how she managed to land a ‘free lunch’ when grabbing a coffee at the supermarket.

Sharing her video from her car outside Tesco she said:  "I just went into Tesco to get a Costa Express Coffee. Costa Express Coffee, regular, £3.05. Make it a meal deal with your Clubcard and it's £3.

"So I've got a salad, a chocolate bar and a coffee for £3 instead of £3.05 for just the coffee. Win."
