Just to warn you if you order a tesco meal deal as part of your tesco.com order.
I ordered a Finest Meal Deal which costs £9 - which includes a bottle of wine worth £8, a main course, side and dessert. It flagged up when I had my delivery that my main course was not available so I had a susbstitution.
However, I did not notice til later that on my receipt I had been charged full price for all the components of the meal deal - this added up to £18!!
I phoned to complain and was told that if the sustitution is not within the meal deal, then they charge full price for all the food.
After a lot of complaining I got some money refunded to me. But beware if this happens to you as it is not flagged up in the substitutions list and can easily catch you out. It is not right that Tesco can so this!
