Google Checkout和促销

Question

I've started working on some enhancements to an ASP.NET web forms e-commerce project, one of the tasks is to add promotion codes to the check-out page.

Currently, the site is using Google Checkout (via the GCheckoutButton that comes with the .NET sample pack), the trouble is I can't find any sensible way to add the promotion to the Google Check-out XML request...

Has anyone done this before, or should I just apply the discounts to the items before putting them into Google?

Thanks, Kieron

这不是完美的方法，但是添加最后一个带有负值的购物车项目以及明智的描述就可以了。
