Ignore the numerous companies advertising letters from Santa for a fee. You can get them without paying a penny, and this includes Braille letters for blind children too.
The deadlines for this year's free Santa letters have now all passed, but the magic needn't end there. You can still send a free personalised video message from Santa, or track his progress as he whizzes around the world delivering presents on Christmas Eve.
Free site Norad Santa lets you watch Santa's progress as he visits the homes of good boys and girls delivering presents on Christmas Eve.
It's great fun for kids, and there's also Santa's Village with an 'Arcade' full of games plus a 'Library' where they can learn about festive tradtions around the world, to keep them entertained as St Nick and his reindeer fly closer to the UK.
Free personalised Santa video
There's a website and app that'll send your friends and family free personalised online video messages from Santa (lasting around four minutes) - incredibly cute for kids and hilarious for adult recipients!
Just follow this simple step-by-step process. To make it even more fun, upload a photo of the person you're sending it to. You'll need the digital photo handy when you do it.
STEP 1: Tell the Santa about the recipient.
Go to the Portable North Pole website or download the app for iPhone or Android and fill in the details, including the recipient's age, whether they've been good or bad (the latter option's only available to adults and teens), their name, gender, where they live and more. If your name isn't in their database you can select from a list of alternative nicknames if you scroll to the bottom of the drop down list.
There's quite a few questions, but it should take less than a minute to complete. The more detail you add, the more fun it is as they'll be mentioned at various points in the video.
STEP 2: Add a photo.
You don't have to do this, but again, it makes it more personal. It can be a JPEG, GIF or PNG file with a maximum size of 3MB. All photos uploaded will be deleted from the site's database before the launch of the following year.
STEP 3: Send to your recipient.
If you want to be able to go back and edit it, save the username and enter a password. Hey presto, that's it. You must be over 13 years old to use the site.
