When an item is in short supply, the supplier may give customers a price discount on the stock-out item to compensate for the inconvenience of backorder and get more orders. 当仓库缺货时，为获得更多订单以及补偿顾客因滞后供给遭受的损失，供应商会给予一定价格折扣。
The blackout forbids publicising price cuts, but there is no matching ban on giving a customer a discount in the run-up to the sales, so long as they ask for one. 这个禁令就禁止了公开的价格折扣，但是对于要卖的商品，没有相配配的禁令能让顾客在促销期后仍不能享受折扣优惠。
