Department store group Debenhams has confirmed it will introduce next day delivery to its customers next year to boost its online business.

The retailer, which currently delivers within 2-4 days, said the launch will help it to achieve its GBP500m (US$772.8m) online sales target in the next three years.

Last month, Debenhams said it saw online sales surge 34.9% during the second half of its financial year.

Meanwhile, sales at stores open over a year rose 3.1%, excluding VAT, in the 16 week period. This helped to lift like-for-like sales by 1.2% over the retailer's first half.
