To close the container I have to also send goods below U.S. $ 4, but do not worry because there will be a low of $ 2.50. You can trust me, it will be a small amount, I go still be very weak commodity here. any questions just ask.

Answer 1

我发给你的包裹原本有15公斤，其中真正的商品没有那么重，剩下的东西我不知道应不应该寄给你，所以我只发了你清单上列出的商品。为了将寄费维持在4美元一下我只好合上容器，不过不用担心，我会尽量削减只2.5美元。相信我，这只是一小部分钱，我的商品一直很实惠。有什么问题尽管问。

有几句很诡异我试着帮你翻了，这段实在是太口语化了。
