This is the time of the year when Britons get their wallets out and spend big online.
Friday (November 28th) will be Black Friday, a day which will see numerous retailers offer discounts on their stocks. This is originally a US tradition, but has now started to take off in the UK.
According to Visa Europe, £1 million will be spent every three seconds across the 24-hour period, as people take advantage of the discounts to do their Christmas shopping.
Another day that will see Brits head to online stores is Cyber Monday. This is the first Monday after the US holiday of Thanksgiving, which this year falls on December 1st. According to IMRG and Experian, a total of £649.6 million will be spent on this date.
It will be followed by Manic Monday - the second Monday of December - on which £676.5 million is forecast to be spent.
However, for online marketplace eBay, the busiest day of the year is expected to occur this Sunday. A statement from the company said it believes November 30th will see the most people buy and sell on the site.
Tanya Lawler, vice-president for eBay Marketplaces in the UK, stated: "This Christmas, above all, people want convenience and selection. Online and multi-channel retailers are able to offer fantastic depth within their product ranges and combine this with convenient local collection services like click and collect."
It is estimated that 1,800 gifts will be purchased on eBay every minute on Sunday, with more than seven million Brits heading to the site over the course of 24 hours.
At present, 258 mobile phones are sold every hour on eBay, while 85 games consoles are purchased. Some 99 tablets are sold every 60 minutes, while 318 handbags are purchased in this period.
These are impressive figures and demonstrate just how popular online retail has become in the UK.
