Events have accelerated changes that were always underway, shocked people into changing habits just like with the MFS and bill paying.
But this is also an example of how those changes are going to ripple out — as with the effect of home working on those sandwich bars in the business district.
This will probably have an effect on the garment industry in Bangladesh.
Because online clothes sellers look for a different set of attributes in their suppliers than those selling from physical retail locations.
Okay, this is one of those things that are not exactly and wholly true — like so much in economics — but which is largely so.
For an internet retailer, the speed of supply is much more important than it is to a brick-and-mortar seller. Because, trends and fashions change both more often and more swiftly online.
Zara, which buys a lot from the Bangladeshi garment factories, is sort of a halfway stage here.
Part of the secret of their success was that they did not run on predictable stock cycles.
They did not have the four seasons of clothes each year running on predictable timetables.
Rather, they had a constantly changing constellation of stock. To supply this, they would — and do — buy some substantial portion of their supplies from the big garment factories.
But when they espied something that was selling well, they would top up that stock with something made in Spain or Northern Portugal.
This is because, the time of supply was vitally important — it takes, perhaps, seven days to get it from Iberia instead of the 60 or 90 days it takes to source it from Bangladesh.
Online takes this a stage further.
Boohoo, one of the largest e-tailers in the UK, might have something in stock only days after it was first seen on some TV programme.
Someone fashionable wears something, folks want it, and it is copied and available near immediately.
To do this, they use UK-based factories. The higher price of manufacture is more than covered by the speed of supply.
