does anyone know how to use a Tesco's code once you have checked your basket out?

I can't find any way of doing it, despite the fact that you can add/change items up to delivery.

Any one know?

I am afraid to say that you can't. I had a huge argument with Tesco's customer services when I phoned them up about it. It drove me mad that they would not honour the code when it was purely an accident that I forgot to put it in. You might get more luck - fingers crossed

You can't. The easiest thing is to start a new order, go to my faourites, click on recent orders and choose the order you've just done. Click on everything once and it will add everything from your order into the basket in the correct quantities. Go to checkout, enter your code and then cancel the first order.

I rang them and they credited my account - guess it depends who picks up the phone!
