Instructions:I got these vouchers through from 'Tesco Healthy Living Club' I'm not sure if you will need to be signed up for the club for them to be valid on your account or not, or if they are personalised vouchers etc, so just give them a go!
They say XX extra points when you spend so much on a certain product, but all 3 were just accepted on my online grocery shop when I hadn't brought any of the products! The vouchers show on the tesco checkout as '80 points when you spend £4.50' etc!
80 Extra Points when you spend £4.50 on Fresh Meat and Poultry - GRTVPK
65 Extra Points when you spend £3.50 on Fresh salad - GRT34B
65 Extra points when you spend £3.50 on Fresh Fruit - GRRTPM
Hope these work for you! (If not, make sure you sign up to the Healthy Living Club (it's free!) to receive vouchers next time!
