Some fruit is a lot more expensive than others. Apples are €2-3/kilo, while blackberries are over €20/kilo.
So he probably bought 7 kilos of blackberries.
Wow. So foreign. Is the E shape a Euro and 7 kilos well I cannot get to google to find out without my page erasing so... Double 7 pounds?
Apples can be expensive anywhere if it is the wrong store. Also Jack fruit and dates are expensive as well but taste so good.
Also where I am from originally, in Washington State, apples are incredibly cheap, so it just depends on where you are at.
