Also I encountered several other oddities. We had an customer who was able to order with outdated prices, and another customer who was able to place an order not only with the discount from another customer (who called to tell us he was unable to place an order) but with several items repeated. These oddities stopped appearing after I disabled this plugin and its extension.
