The Royal Mail has launched a trial of evening deliveries to help people not at home during the day to receive parcels or other items.
The six-month trial for anyone living within the M25 area in London and the South East will cover goods ordered online with House of Fraser and beauty product firm L'Occitane, although the Royal Mail said it was in talks with other retailers about joining in.
Royal Mail director Mike Brown said: "Consumers increasingly want more control over when and where they receive their orders, and Royal Mail is looking to fit the online delivery experience around the shopper, enabling them to select, rather than being told, when their goods will be delivered."
The online retail market is expected to have annual sales of £56 billion this year, with a recent study by Royal Mail showing that 58% of people would shop more online if there were more flexible delivery options.
The trial enables shoppers at House of Fraser and L'Occitane to ask for items to be delivered between 6pm and 10pm.
