Okay, but please consider the problems reported by fodder in this thread--caravans are not buying all the food they should.
If there's an auto sell at 20, max 200 bushels, and a manual sell at 20, for another 200 bushels, then a caravan SHOULD be able to purchase all 400 bushels, as long as the caravan has sufficient gold and was told to buy at 20.
Is this the way it will work, or will two caravans need to be sent?
