Hi,
Eliot forgot to mention that this feature is in HikaShop Business.
He also forgot to said that you can acecss to the email content in the "media/com_hikashop/mail" folder and by creating a copy of the mail with the extension ".modified.php" you create an override.
After that, you are right, the language key for the shipping is the wrong one. The shipping method is not displayed in the email but the shipping price is.
We will fix the content of the email, to display similar data than the invoice. We also have some "issues" in our tracker to rewrite the emails design and improve the email editor. Maybe at this moment we will provide the simple editor in all HikaShop edition and provide the advanced editor in the Business one.
What you can easily do in all HikaShop edition is to change the texts in the email. Like everywhere in HikaShop, we don't use hard coded text but translated text.
The email is not an exception and it uses a lot of translation that you can change and override like you want.
I don't want to make a big Laius on it but, we won't include all features in the free version of HikaShop, we have to pay our employees too.
With the starter edition you can create an e-commerce website and sold your articles. You can also customize your emails, your views, edit the files that you want to edit. HikaShop is open-source so you have the right to access and edit the source code.
Regards,
