The reason why half a piece of cashew nuts is cheap: half a piece is defective. Half a piece of cashew nuts is definitely cheaper than the whole cashew nuts. The whole cashew nuts are genuine, while half a piece is inferior. That price must be different. A cultured person won't buy half a piece of cashew nuts like that. Just like buying fruits and vegetables, half of them will definitely not be bought by anyone, and they will definitely have to be sold cheaply.
