A strong rise in sales on Very.co.uk delivered Shop Direct record Christmas trading results in the seven weeks to December 25.
The online retail business, which also owns Littlewoods.com and VeryExclusive.co.uk, said group sales were up 6% year-on-year.
Sales on Very.co.uk increased 17% compared with the same period last year, with clothing and footwear up 6%.
Mobile transactions on Very.co.uk increased 32% year-on-year, making up 63% of Christmas online sales.
The trading period includes the Black Friday weekend, when sales increased 64% against 2014.
Shop Direct now expects Very.co.uk sales to reach £1bn in 2016. It did not break out the other two businesses.
Shop Direct has also used the update to announce a new £50m personalisation programme, in partnership with IBM, for its payment plan services. More details are expected to follow.
“Received wisdom is that every retailer should be multichannel. We don’t buy that,” said group chief executive Alex Baldock. “We like being a digital pureplay. It allows us to keep things simple and focus our energy on mobile innovation, which has been a big factor in our record peak trading.
“On the back of a strategy that’s working and a successful peak, we’re now well on track to deliver another record-breaking year of sales and profit.”
