If you're planning to do any part of your Christmas shopping online you will want to be sure your order will arrive in time. Here we round up the final order dates for some of the UK's biggest retailers and charities. We will add to this and update it as Christmas approaches.
Unfortunately, things like a sudden snowstorm could disrupt even the best laid plans, so the message for all shoppers is if you want to be sure you get what you want, don't leave it to the last minute.
