Mark & Spencer's online customers are set to be disappointed this Christmas shopping season, as they face longer waiting times for online deliveries.
Standard deliveries will now take up to two weeks, according to the retailer's website, as opposed to the normal five-day waiting period.
The delay follows shopping bonanza Black Friday, on 28 November, during which retailers slashed prices on a range of products.
This was the first year the British high street really embraced the US import, and UK shoppers are thought to have spent around £810m according to Experian and IMRG.
A spokesperson for Mark & Spencer told the BBC:
Our customer is always our top priority and that is why we've extended some of our delivery options.
It also said the service, which lets customers collect online orders from a store near them, currently takes just two days.
However it will still have to contend with an influx of orders from so-called "Manic Monday", which kicks off today, and is another huge shopping day for the Christmas period.
The company's shares were down 3.2 per cent in mid-morning trade.
