Indeed, it sounds pricey. I had to pay around $USD14 for 3 large durians.
Since they come from so far away from where I live, I've seen one or two durians in the health food store (they have a larger variety of produce there), but they are $20 US for one! So I've never had it. It was the size of my head, though. 😂
Durian has many varieties. In here there is $15-20 per seed not per fruit 😅
