Do you have lots of Tesco Clubcard Vouchers?
 

Well, you can trade them in for 50% off on wine. Just saved myself £250!

Double Up on Clubcard - Tesco.com

It's probably the best deal you can get with clubcard voucher at the moment.

Also, they have a higher value by up to x4 face value with some other companies - we have used ours to pay for our eldests' birthday party at Tenpin in Northampton £ 30.00 of Tesco's vouchers = £120.00 of purchasing power at Tenpin and many other places.
Birthday party paid for in January:)

the details are on the tesco website.

You can get 4 x the face value if you trade them in for food vouchers at certain restraunts, again on the website.

Changed a few hundred pounds worth of points for Airmiles. It's helping to take the family for a short break to Disneyland Paris! Makes it worthwhile reusing the carrier bags and using the recycling machine (1 point per bag and 1 point for every 4 recycled cans/bottles etc).
