Hello
Is it possible to change "kilos" or "Liters" or "pcs" to Persons?

And the texts like "Checkout" to "register now"
"Back to Shop" to "Back to Tours"

In which file do I have to make the changes?

Also I want to make a shop for Tours. It should be possible to give one price for Single Rooms and a Rabatt Price for Double Rooms.
Is it possible to do this with joomshopping?

Thank You
Uta
