Saw a poster for this in my local, I believe it was previously double the value, it is now 4 times the value. I think it's a fab idea if a group of people are wanting to go out for a cheap meal.
Info from their website http://www.smithandjonespubs.com
Smith & Jones pubs are pleased to accept Tesco Clubcard Reward Tokens towards payment of food.
Through their highly successful Rewards Tokens scheme, Tesco will convert your Clubcard points to four times their value to spend in a variety of lifestyle outlets. For example, your £10 in Clubcard points will convert to £40 in Rewards Tokens to spend in a Smith & Jones pub.
To convert your Clubcard points to Rewards Tokens, visit the Tesco Clubcard website.
To spend on food in a Smith & Jones pub, simply present your token as full or part payment towards your meal.
