Should the Royal Mail only do three deliveries a week?
The Royal Mail has announced a drastic drop in profits, because basically, everyone is sending fewer letters, and thanks to increased competition in the parcel game, the Royal Mail is seeing less go through their hands too.
So what happens next?
Well, an economist who appeared on BBC Radio's 'Wake Up to Money' has had an idea - that the Royal Mail can't deliver our mail 6-days-a-week any more, and their business be relevant.
With that, Ian Senior thinks that deliveries should be dropped to three per week.
He said: "The business is still viable, particularly on the parcels side."
"You have to realise that value of delivering a parcel is going up, the value of delivering a letter is going down. The great majority of letter mail is not time sensitive anymore."
The Royal Mail, of course, aren't having that. A spokesperson for the postal firm said: "We do not agree with anyone who says that the Universal Service specification should be cut to three days a week."
"The six-day-a-week service is a key part of the Postal Services Act and we are proud to deliver it."
Just how big was the profit drop? Well, in 2015, the Royal Mail made £400 million, but at the end of March, that was down to £267 million.
That seems like a lot of money, but profits would have been considerably lower if the Royal Mail hadn't sold their Paddington depot.
Royal Mail added: "The UK letters market has been subject to a structural shift away from paper-based communication to electronic communication for a number of years now."
"Given this structural decline we are focused on promoting the value of mail through campaigns such as keep me posted and optimising mail handling within our operations to accommodate a changing letters mix and increase efficiency."
