The recent national postal strike causes a huge slowdown in the growth of online sales of goods according to a study by IMRG Capgemini.

Sky News reports that the firm’s e-Retail Sales Index show that in the last week of October – when strike action was at its largest – online sales dropped by 5%, leading to a £53million fall in sales.

The IMRG Capgemini e-Retail Sales Index showed British shoppers spent £4.2 billion online in October, an increase of almost 12% on the same month last year.

Consumer confidence in Royal Mail’s ability to deliver goods bought online was a major factor in October’s e-retail sales values and volumes decline but with the threat of further industrial action averted in the run-up to Christmas, it is hoped that shoppers’ doubts and concerns can be alleviated.

Mike Petevinos of Capgemini said: “E-retailers must ensure they heed the October warning signs and act to reassure consumers that orders will be delivered in time for Christmas.

“With consumer confidence restored, e-retailers can get on with the real challenge of convincing consumers to spend online and resist the temptation to wait even longer for last minute discounting on the high street.”
