The Prince and Princess of Wales have hardly spoken to the Duke of Sussex following the publication of his memoir.
Now new data shows that interest in Prince Harry's book has waned.
The Knowledge Academy has found that Spare is among the top ten least valuable books based on its resale value.
The Duke of Sussex's memoir is ranked eighth on the list that uses the original price of a book compared to its resale price to determine its value.
Spare sells for on average just 34.77 per cent of its original price, according to the data.
In July, Prince Harry's autobiography was causing chaos abroad as hotels rushed to get rid of the unwanted book.
More than 100 copies of Spare had been left abandoned in resorts across Europe as tour operators have struggled to give them away.
On The Beach, the online tour operator said it has received many discarded copies of the Duke of Sussex'a autobiography from resorts in Spain, Turkey and Greece.

Zoe Harris, the company’s chief customer officer, said her team had "never witnessed anything quite like it".
Harris said: "Lost property offices in our most popular resorts are brimming with copies of Spare, and we had a couple of Prince Harry’s books sent to us from a hotel that some of our customers had holidayed to.
"We thought it was quite funny at first.
"But over the past few months, several other hotels have been sending the books back. Now we have bookcases full of them.
"I’m asking hotels to please stop sending them over, otherwise we’ll never get rid of them all."
