Find vouchers on the back of Nestle cereal packs and Rowntrees sweets and a range of other products.
The voucher entitles you to free sports activities at leisure centres around the country. Last year I saved a packet getting free Badminton courts which are usually £9-00 a time. It is almost worth buying the cereals just for the vouchers!
Valid for tennis, badminton, swimming, football, golf , squash, martial arts and dancing lessons.
