The other option for implementing dynamic pricing in Nosto recommendations is by using price variations. Please see this article how to tag the price variations. Also note that this method is suitable only if you have dynamic pricing rules (tax rules, customer groups, location or whatever changes the pricing) available in your e-commerce platform backend and the dynamic price rules are rather simple. With complex dynamic pricing rules we suggest using "proxy recommendations" 

When implementing dynamic prices with price variations you must create all combinations that can be derived you dynamic pricing rules. One of the most common cases is that visitors will see different prices in different countries. Too keep things simple we will use two currencies and two countries in the example below. 

Step-by-step example

In this example we have configured different prices for visitors from two countries, United States of America (US) and Finland (FI). We are also using two currencies USD and EUR. Visitors can freely choose to view the store in either of the currencies. 

We need to generate price variations for each combination of country and currency and we also need the default one since our visitors might be located outisde Finland or USA. Our product has a base price of 50 USD. We will end up having following price variations.

You need to also define nosto_variation (active variation) for each page. This variation would be the combination of country and currency code or if the visitor is outside of USA and Finland we would use "default" as a country. You can find more info about the variations tagging from here.  

Complete product and variation tagging would look like this when visitor is from USA and using EUR as currency.
