I need to install a template or a module plus a solution with PHP or joomla module or prestashop extension .....for prices per group for a single product (not discount).
When an user not logged visit the web, a small input form ask for the postal code zone and after that load the web with the prices for his group (by postal code). He can change the postal zone and the shop will reload again.
I prefer to use a template with a commerce solution.
I am open to new suggestions.
I need the solution "how to do it",
