Anyone for scones?

The husband of one of Marc's colleagues is in the Bangladesh army so she can get flour at army rates. Today she turned up with 5 kg of flour for us for our new house. When we asked the price she said it was 85 taka (75p)! But next month we can get it on her army ration and then it will only be about 2 taka!  We were wondering how we would go through 5 kg of flour a month...
