Boxing Day is expected to be the biggest shopping day of the year.Reuters

On your marks, get set, shop! Boxing Day is almost here bargain hunters.

Many retailers are predicting their busiest Christmas yet following the success of Black Friday and Cyber Monday just weeks ago.

Although some brands are likely to still hold out until midnight on 26 December to start slashing prices (cough, cough Zara), many have bucked the trend and either have discounts already underway or intend to start their sales a day early on 25 December.

The sales will run right through to January, when there will be even more discounts available on fashion, cosmetics and accessories.

Topshop

Although Topshop has not officially released a Christmas sale start date, Boxing Day is a safe bet. But if you can't wait until then, discounts of up to 80% are available online and in-store on selected lines.
