The busiest day ever for online shopping will be Monday 1 December 2014, according to a prediction from online giant Amazon.
On that day - which has become known as "Cyber Monday" in the UK - retailers will discount thousands of products in a bid to tempt Christmas shoppers to part with their money.
As a result, it's predicted that millions of shoppers will rush to buy gifts from online retailers such as Amazon, eBay and Play.com armed with their last pay cheque before Christmas on Friday 28 November.
Having spent the weekend browsing the shops, by Monday they're ready to purchase online and take advantage of one-day only savings.
Cyber Monday falls three days after Black Friday - the day US customers have traditionally hit the shops to take advantage of post-Thanskgiving discounts.
Last year, more than 4.1 million items were ordered through Amazon on Cyber Monday, at a rate of around 47 items per second, with sales reaching their peak at 9.22 pm.
During its busiest trading day of 2013, delivery lorries left the retailer's fulfilment centres on average every 93 seconds.
This year, Amazon is promising more than 3,000 special deals, "saving customers millions of pounds" during its Black Friday Deals Week - which begins at 8am on Monday 24 November and ends on Black Friday (28 November), and is targeted at US and UK customers.
New deals will launch every 10 minutes "with offers on everything from stocking fillers to fine jewellery", said the retailer - while pointing out "in previous years, the most popular Black Friday deals were snapped up in seconds".
Last year's most-popular bargains included signed albums from the likes of One Direction, James Arthur and Robbie Williams; a 500GB Sony PlayStation 3 deal that included the game Grand Theft Auto V; a Nintendo 3DS Bundle and a Nespresso Coffee Machine Bundle.
This year's deals will be announced just before the start of Black Friday Deals Week, and more deals will be announced from other major retailers on Cyber Monday - including John Lewis.
To meet expected customer demand, Amazon.co.uk is taking on more than 13,000 temporary staff as well as creating 1,000 new permanent jobs.
