I couldn't get this to work in 2.2. I tried but unfortunetly didn't have the time to proceed my bugfixing. Please do not use this repository it will break your store.
Zone Pricing is an extension to Spree that uses the predefined zones to determine the price for a particular product variant. For example, this allows you to set different prices for the North American and Euro zones.
A new country selection dropdown has been added to the header that allows the user to select their country of choice. The selected country is used to determine the zone which in turn determines the prices for all product variants. The customer is able to select the most appropriate country, all product variant prices as well as items in the cart will be changed to reflect the prices of the selected zone.
The country selected by default in this dropdown depends on whether the customer is a guest or has logged in as a registered user. If the customer is a guest then the country is determined by the setting in the Spree config for "default_country_id", if on the other hand the customer has logged in as a registered customer the country is set to the "Ship To" address country.
When the customer decides to checkout the extension will check the "Ship To" address country against the currently selected country, if they are different the zone will be changed to the one that includes the country selected in the "Ship To" address. Prices of items in the cart will be changed to reflect the change in zone.
