As you're hunting around in search of bargains online, a number of scams, tricks, and general dangers lie in wait for the unwary shopper. Fear not, though, as we're here to explain how to stay safe.
Tip 1: Use common sense
We all love to save money, but criminals know this all too well and use our frugality as a classic scam to part us from our cash. No doubt your inbox is overflowing with emails from companies offering deals and discounts for a variety of products. Many of these will be genuine, but the general rule of thumb online - as in life - is that if something seems too good to be true, the chances are that’s probably the case.
You might see sensational deals for cheap products advertised on Facebook or by email. People you know might have shared these offers with you. Just be sure to check out the website and satisfy yourself that it is a genuine company which won't just take your money and run. Recently we saw ads for electric bikes at unbelievable prices under £100.
Sure enough, when we looked at the website, the bikes had no descriptions or specifications and we couldn't find a company address on the 'About us' page. All red flags which should alert you to a scam.
If the email is from a reputable site, simply navigate to the site yourself in a web browser and the deal should be available. Criminals sometimes set up sites that look exactly the same as the one you’re expecting (at least for a page or two anyway) and it can be an easy mistake to log in, then get a nasty surprise when you don't receive the goods or your bank account is emptied.
If you're shopping for technology and gadgets, be sure to browse our hand-picked best tech deals.
Tip 2: Use well-known websites and security software
For the reasons above, it's a good idea to stick to using websites for companies you know. Amazon, John Lewis, Argos: you get the idea. We'd even spend a few quid more on a product from a company with a no-quibble returns policy.
Even if you're using a well-known brand, we also recommend you install some antivirus software which includes a website checker that will give you the green light that tells you the site is secure and safe.
In fact, you can download McAfee's SiteAdvisor for free if your current antivirus doesn't include such a feature.
And if you're using a smaller online retailer you've never heard of, Lesley Cowley, chief executive of Nominet, says it pays to "take a few minutes to search for the company on the internet and check their reputation".
"Look for a telephone number for the company. Ring it and check it works if you have any concerns," said Cowley. Telephone numbers, providing they're genuine and in use, are a good sign, email addresses and the lack of a postal address should set alarm bells ringing.
It might seem harsh, especially for enterprising small businesses, but our advice is simply to shop on sites that you know to be reputable - or at least an ongoing concern - rather than take a chance on an obscure outlet that might be gone tomorrow.
Tip 3: Check before you checkout
Jon Callas, CTO of security solutions firm Entrust, warns users not to let their guard down when they hit the online checkout. According to Callas, you need to look out for several things before entering your credit or debit card details into a website.
"If the site has an EV (extended validation) certificate the address bar will be green and the business name will be readily visible," he said. This means that the site has met a specific set of security guidelines which are independently verified, and that the site can be trusted.
Secure Sockets Layers (SSL) are used to ensure data is encrypted before being transmitted across the web and also indicate an organisation has been verified. Callas says potential purchasers should keep an eye out for https in the address bar rather than just the standard http, as this highlights a site uses SSL.
You should also look out for the padlock icon somewhere in or near the address bar, which is one of the main security features of basic SSL.
"Depending on what browser you use, it might be on the address bar or somewhere else like the title bar. But if you click on it, you will see security information about the site you're on," he said.
Furthermore, respectable organisations will display the site seal of their SSL certificate provider either on their home page or during the checkout process. He also recommends clicking on the site seal to ensure it's legitimate. You should also verify that the date and name of the organisation are consistent with the site you're visiting.
Those using public Wi-Fi, especially if it's unsecured, need to be extra careful as "you never know who could be listening", according to Callas.
"Double-check that there's SSL, and that the certification is good. Be extra, extra careful on a public computer; don't do anything financial or involving a password unless you must, as these are easily riddled with malware."

Tip 4: Check delivery times
One of the advantages of going to the high street is that you return with your presents under your arms. Online shopping saves the trip, but means you have to wait for delivery.
Of course, sites such as Amazon offer next day-delivery at a price (or as part of the Amazon Prime service) but you still have to be in to receive them, and delays can happen at Post Offices with the huge amount of mail that goes through the sorting offices, especially at Christmas time.
Always thoroughly check the availability of items before you click Buy, and remember that Amazon also lists products from other companies that might not be based in the UK, so make sure you check that you're buying from Amazon rather than a 'marketplace seller'. Or, make sure that the seller lists a suitable delivery time.
It's similar with ebay. Don't assume the company you're buying from is in the UK, even if their contact page says they are. Many China-based companies put 'UK' or 'London' as their location in order not to put off buyers, but check the delivery estimate and also the seller's recent feedback to see if they can be trusted to deliver your stuff quickly.
Tip 5: Click & Collect
An alternative to delivery is click & collect. Many big-name sites offer this now. For example, you can collect many ebay products from your local Argos store. Amazon has lockers in quite a few places now, so you can collect your items at a suitable time to you, and you can specify where they're delivered to.
Most supermarkets also let you order online and collect in store, but do watch out for any charges as it isn't always a free service.
Tip 6: Check returns policies
Sometimes you'll need to return an item that doesn’t fit, or find that there's a problem with a present purchased for someone else. So before you buy, check the return period if you are buying a gift.
Many retailers extend this beyond the usual 30 days over Christmas, but don't assume they all do. Ideally, open the packaging and test out what you buy as soon as possible, rather than wait for Christmas day and find out it doesn't work.
