correct prepositions

[Hanka]

Hi,

could you please help me with the following prepositions:

1) The goods shall be delivered by a freight forwarding service or by post.

2) The Manufacturer undertakes to provide basic technical training on products for the Purchaser.

Thanks a lot!

They are fine.

I don't think you need "for the Purchaser" in the second sentence, unless the manufacturer does not usually offer training.
