1--Our usual supplier has let us down and I’ve been looking through your parts catalogue. I need fifty GT670s. How soon can you deliver?
 
2--Just a moment and I'll check. We’re expecting a delivery on Friday. We've only got ten in stock at the moment. I can deliver those by first thing tomorrow morning. There'll be an extra charge for special delivery. I'll have to send them by courier.

1--我们经常供货商让我们失望，我在看贵方的配件目录。我需要五十件GT670s.。你们多快能发货？
2--稍等片刻，我查一下。我们预计在星期五发次货。我们目前库存只有10件。这些我可以明早一早就发货。对于快递需要额外收费。我把货送给送件人。
