Up to now Marks & Spencer has only sold about 15% of the brand's homewares and clothing in sales online (compared with Next, which does around 35% in online sales), but that's about to change now that M&S opened an automated 900,000 sq ft warehouse this week in an effort to improve service for online shoppers. The new Castle Donington warehouse is expected to be able to handle a million orders daily.
