Noticed this a few days ago, but just thought maybe I couldn't find the rule I was after but it has been changed. This rule being the "bulk sales" rule.
It used to be no more than 2 of any one item. I think this worked. It was a set limit, black and white. Now we have a no bulk sales rule which has opened things up.
Just wondered why this was removed. I personally think the 2 rules should be run alongside each other. No more than 2 of an item, and no bulk sales/purchases.
