M&S has unveiled 12 days of prizes and offers as we enter the Christmas countdown.

December 1 marks the first day of the retailer's digital advent calendar.

Every day from December 1 to 12, Sparks customers can access a festive offer to use across its range from M&S Clothing, Home, Food and more.

There is an exclusive deal behind each door that customers can only open and claim on that day.

On one of the 12 days, shoppers will get the chance to enter a draw for two tickets to a Sparks VIP Gary Barlow Christmas performance and Q&A.

There are 100 pairs of tickets up for grabs to the exciting London event which is taking place sometime before Christmas.

Other prizes include 100 signed copies of M&S Brand Ambassador Holly Willoughby’s new book Reflections as well as 5 personal Christmas video messages from England Rugby star and M&S Brand Partner Maro Itoje.

There is also a chance to get discounts off your shopping at M&S including 25 x £1000, 100 x £500 and 100 x £250 M&S gift cards and 100 M&S Snowglobe Gins.

How to access M&S 12 days of Christmas discounts

To make the most of the discounts, M&S has told customers to make sure they are signed up to Sparks. 

Customers also need to download the M&S app on their smartphone to access the calendar.

Any doors not opened will expire at midnight and cannot be claimed retrospectively.

The validity periods will vary with food offers being valid for seven days while partnership offers may apply for longer.

M&S has said that the calendar is an added bonus to all the benefits you get as a Sparks member.

These benefits include the chance to win your shopping for free via its surprise & delight feature at every M&S store each week, and donations to the causes that its customers care about.

Danielle Papagapiou, Head of Loyalty at M&S said: “Through Sparks we're aiming to help our customers have the most fantastic Christmas this year, and we've pulled out all the stops to offer 12 consecutive days of M&S offers, treats and rewards to kick off December.

"Each day we'll be offering a new surprise for every customer in their Sparks hub on the M&S App and hope it will add a little bit of M&S Sparkle to their festive shopping this Christmas."
