如果是按中文意思這是delivery needs time
如按英文意思是「交貨期」 - 由落訂至出貨時間2. Style and Color can be selection. 款式和顏色均可選擇

5. The customer needs to make 50% deposit and pay all the remaining on delivery. 訂造物品時，客戶要先繳交50%的款項，餘額便要交貨付清。

6. The account will be canceled if the customer has taken an order during a year. 在一年內，貴公司沒有在本公司下訂單，所持戶口將會被取消。

8. takes 90 working days of delivery 交貨為90個工作天

9. Above products made to order 以上產品均需訂
Above products require order in advance.
- Above products are made to order未必是錯，不過一般意思是由客人設定或選取所需要的配搭和材料等(例如獨特的車輛或如組合切成的電腦)，但如果只是說貨品不是off-the-shelve有存貨即訂即有，需要預訂或提早預留貨(可能每月只生產一定數量)便用我的提議。

問嗰個都好自為之,你試想想在香港不懂英文的人,大多都做保安,快餐店.你今心嗎?
