I personally haven't had a clubcard for too long and its only recently i have realised that i have been wasting my clubcard points as i was not aware of what you could actually do with them.

To get one is free all you need to do is pop in to your local Tesco shop and ask for a leaflet, inside the leaflet you will get a paper version of a clubcard that can be used until you receive your real one in the post.

To sign up you can do one of 3 things, go online and fill in your details, you can give your details in over the phone, or inside your leaflet are questions asking for your information, you can fill that in and pop it back in the post to tesco and hey presto your card shud be with you with 6 weeks.

Once you have been usuing it for a while you will be sent out vouchers for tesco which you can use for money off in store or you can exchange them on line for vouchers for soooo many other things including anything from days out, to meals to magazine subscriptions, i personally would say that your much better off exchanging your tesco vouchers for the others as you can then multiply there value up to 4 x
