I didn't know this place had such a good collection of books. I bought a book named 'Ar-Raheeq Al-Makhtum' from this place, which I did not expect them to have. The prices are not very high, as you might expect from such a place. Instead, I found the prices very very reasonable, and far lower than their online counterparts.
As a side note, I noted that you can find here the books on Islamiyat, books on tafseer of Quran (like Tafseer ibn-e-Katheer), Qurans, storybooks for children and elders (in English and Urdu), novels (in the both languages), textbooks for kids on different subjects (like science, English, maths, etc.), and some books on history.
