Hi

please how can make product price shown to customer depending  on his country ?

as example

** if i view site from Egypt >> Get price for all products with "Egyptian Pound"
** if i view site from USA>> Get price for all products with "$ Dollar"
** if i view site from Saudi Arabia  >> Get price for all products with "SR"

Out of the box it's impossible. In the GrandNode 4.40 version we are planning to implement new feature related with prices, but it won't automatically detect customer currency. It can be assigned to store. If you want to create it in current version, it need to be a customization.
