Nice post. However, these biscuits, in English, are called Rusks. In Greek, paximadia. In Spanish, according to Google, 'Bizcochos'.

In your own language, you do not have a special word for them, you just call them toast biscuits?

As for the price, over here in South Africa, half a kilo costs more than $3 (upto $6 if they describe them as 'home-made'). I too would eat more of them if they were so cheap.
