Clubcard rewards are worth four time as much as the quarterly vouchers received in the post lots of people I know just spend these in Tesco but we save ours and use against holidays. You need to check where you want to spend the vouchers and then redeem for the company in question. If you look at Tesco website it gives details of companies participating in the scheme. Unfortunately Individual travellers stopped at the end of September but holidays already booked are covered till December. Cosmos are still showing as participating and they do villas in Pollensa but the vouchers are only against the full package flight etc. Have not tried these but def. recommend using the scheme for hoidays so far we have been to Paris, Las Vegas, Boston, Sorrento and Pollensa twice, plus the reservation for December all with considerable discount.
