Not for points English to Chinese Law/Patents Law: Contract(s)

In the case of an order deviating from the complete package offer, the seller shall be entitled to adjust the price accordingly.

當個別訂單內容有別於完整的包裹式報價時，賣方有權依據該差異調整價格。

Question:
In this paragraph of the English contract, "package offer" has been translated as "包裹式報價". Is there any other terms that shall better fit this context?

Thanks very much!
