Post early for, umm, Tuesday?
Make the most of this coming Sunday's post collection - it's the last one. The Post Office is stopping Sunday collections from the 30th September. They're stopping Bank Holiday collections too.
And they're even considering stopping Saturday deliveries.
Suppose they do that. If you post something late on a Thursday evening, first class, it might be delivered on the following Monday (or Tuesday if you're unlucky). Not first thing, either - remember that the post delivery is later nowadays. So it could take four or nearly five days, first class, even if it's not a Bank Holiday weekend.
Apparently all this is to save money, because of the competition from texting, email and mobile phones. But it's not exactly going to encourage people to send letters, is it?
