Completing the text in the store

[Fistzilla]

Hello!
In Germany it is a law that the price of each item must always be "incl. VAT plus shipping".
This text is obligatory.

I cannot find the place in the files to add this text.
Who can help me?
It is needed in the store and in the individual view of the article.
I have shown the graphic how it must look like.

Thanks a lot!
