I sign up for every loyalty scheme available. It is a hobby of mine and it lets the marketeers know that some men shop for their own needs. You might think they would know this already but apparently they need to find this out by analyzing marketing data. Furthermore it is possible to game some schemes such as this one from Tesco.
The way to maximize the value of Clubcard points is to exchange them for something not offered by Tesco. This can multiply the value up to sixteen fold.
The best value to be found is almost certainly the £10 'finest' meal deal.
This offering has improved under 'Drastic Dave' who is trying to rescue the company. It has become less 'poncey' and offers seemingly basic but top quality food made from the best ingredients. I was impressed.
What to do now? Get yourself a Tesco Clubcard!
