Parcel deliveries in the UK

"Britons are keen online shoppers, with internet sales as a per cent of the overall retail spend outstripping even the US. According to Boston Consulting Group, online retailing is expected to account for 23 per cent of the UK’s total retail spend and 12.4 per cent of GDP by 2016.
Data from PwC show the UK parcels market has risen from about 1.3bn items in 2005 to 1.7bn items in 2012 and is expected to rise to 2.3bn items by 2023.
The evidence is borne out in its own post room – PwC said that its offices on the banks of the Thames had received up to 6,000 parcels from retailers such as Amazon in the past few weeks, double the usual level."
