Just got an e-mail from Tescos:
Dear Ikaz,
If you've made a resolution to save money after Christmas, why not shop with tesco.com and let us help you make your money go further.
Buying groceries online is the simplest way of sticking to your shopping list. It means no impulses and no pester power. We even keep you up to speed with a running total as you shop. And as all the regular in store offers are grouped together, you won't miss out on savings either.
What's more, you can now collect up to 1000 extra Clubcard points* when you shop this New Year.
I got 3 codes to use for 200 extra points per £50+ shop, and once I have used all 3 I get an extra 400 points.
