How to win these three fantastic prizes

To win Tesco shopping worth £2,600, all you have to do is collect the numbered vouchers over the next three weeks, the first one appears in this week's copy of your local Guardian, out today. Please note photocopies will not be accepted. 

On the third week, you will be asked to answer a competition question, send in the vouchers with the entry form (address and form will be provided nearer the time).

On week three, the competition to win a Champneys spa break will begin with the first of three vouchers to collect, and then our mystery prize will be the last competition to run.

The competitions will run until January 17, when all three have appeared.
