Just thought i'd share this that I spotted the other day whist on CokeZone. It's difficult to obtain these vouchers when they're not in papers or on the back of cereals etc.
For just 5 cokezone points, you are able to get a discount voucher for loads of UK days out like:
Alton Towers resort,
Chessington World of Adventure
Sea Life Centre
This can save you a small fortune.
To get this, simply sign up to CokeZone. You will be given a 2 point start up bonus. On the second page of the sign-up, you will be asked to take part in their survey (which you need to fill out anyway to receive your rewards from CokeZone). This will grant you a futher 5 points.
* If you are already a member of CokeZone and are not entitled to the bonus, a 2l bottle grants 3 points *
* Free points available for doing Coke polls, games etc, see fun
