Adding a default delivery address to users when pickup in store

[nal]

Hi,

 

Here is my issue for a shop established in Switzerland but close to the French and German borders.

 

If users choose pickup in store (Switzerland) the but have their delivery address in France or Germany then the VAT is not included but it should as they pick it up in Switzerland.

 

So, my thinking is to add the Store address as delivery address for the users when theychoose pick up in store option.

 

It my thinking right? Can you guide me as to which hooks and functions to use?

 

Thanks

Nicolas
