The 9 books are complete.
They are sold at Jarir as a set for 399.
I bought six of them in a set for 249 and the three others were 49 each.
So the purchase price was 396.
Selling price for all of them is 250, negotiable.
For one book, it's 30 riyals, also negotiable.
The books are all clean and like new. Their spines are not broken and nothing is written in them except for the first book, and I have photographed the pages with markings.
