Thank god I learned a profession.

The card isn't the problem, running up a debt (taking the credit} is.
I've had a credit card for about 50 years and always paid the dues before the month ended.
But virtually all payments are done via a debit card, cheaper for me and the seller.

I assume many people will just decided based on the price, more expensive should be better, right?

When things work out according to Trump the USA will have plenty of Rare Earth Materials in a place without significant population, Greenland!

The type of 7-segment timekeeper you think off requires power, probably as a battery. The round clocks can be run by a spring or weight.
Yes there are electrical clocks all over the place but there's nothing wrong exposing children at an early age to these fundamentally simpler systems.

Or a (Chinese) $5 analogue wall clock.

That's why we pay by card :)

My memory is that when aged 6 we were told to be at a certain time in school.
The way to know the time was to look at one of the many church clocks around, all of them only showing dots, not numbers.
A few years later we learned what the Roman numericals on our home wall clock and the large clocks of the water tower meant.
Yes life was hard in those days :)

Where I live all church towers have analogue clocks, in my town even the water tower has four (very large) analogue clocks.
And in a typical village there are at least three churches.
When looking around furniture stores the vast majority of wall clocks are analogue.

True.

A problem might be Denmark has a King :)
But yes, I understand your plan.

The price was indeed an important barrier,
Living in the south we mailed all our Christmas cards and letters from Germany, even those addressed to Denmark.

Similar in Denmark, here it is borger.dk that makes virtually all official correspondence available.
I am Dutch and there we also get most official mail via 'the net' on mijnoverheid.nl.
The one EU country still massively lagging is Germany, they say it's because they are a federation and every state has their individual system(s)...

This is relevant to most, this is only the first country ending regular postal services, others will follow.

Being in Denmark I can tell you DAO will accept and deliver letters, both from abroad and in country.
They even can out with their own stamps.
Th old(?) PostNord will limit itself to packages, the stuff DAO did before.
And I wonder why I often call them DOA...
