First time online shopping for food

[poppy101]

Quick query for Tesco shoppers, put in a shop, managed to use a discount code to get £10 off.

Have amended my order, but new email from them doesn't mention anything about my £10 off or total delivery price.

Is this usual and will I still get the £10 off.

Anyone know, as I haven't used TESCO online before for food shop.

I haven't used Tesco for ages, but I think in general total prices aren't given until delivery, as it all depends on weights of any loose items, such as fruit & veg or meat.
