The german market needs are not so difficult to do. I would not use a modul for all these specific needs.
you need a notice near every price:
"inclusive tax or exclusive tax additional delivery cost "(if you have some)
Sometimes the transportation cost is a hoover or link with more exactly description. You do not need the link if you have a link to a delivery cost site easy to reach at the side.
I would do this in the template.
b) you shoud have maybe the first 100 letters of the product short-description in the basket before a user can buy finally. This to show some more detailed what is ordered, because germans are not able to check before what they want to order…
c) The last BUY button you need the german word BUY or similar.- I would do this in the template for example
d) if a product is sold in packing units, for example 0,5 kg, the shopsystem should be able to calculate how much is 1 kg and write this near the price.
e) Some links to special sites like Impressum, delivery cost … normaly it is made with a build in cms system: Why prestashop s cms don t use the user group authorizations like the categories?
f) in the last order confirmation / check-out site a check-in field to "confirm the stupid german regulations " …i don t know in englisch exactly…
g) in the basket and order confirmation / checkout the tax as a single position.
h) in the basket a drop down menu with different countries what shows the delivery cost if you deliver to different countries. ( or you find out where the customer want to be delivered before he reach the basket - ). Maybe also the tax of the delivery cost, but not sure.
what more ?
(If somebody is able to write in more useful english, please improove )
