Hi Cath88,
That was indeed the solution we wanted to propose.
For example: when you selected USD currency for your feed the plugin will put prices in USD in your product feed but you also need to add this to the link:
&aelia_cs_currency=USD
or:
?aelia_cs_currency=USD
(when you have no Google Analytics or AdTribes parameters in your links).
You can append this to your link by adding it in the Suffix field for the link mapping you created. Like this:

Bear in mind that adding parameters to the link has only been made possible a couple of releases back so please make sure you are on the latest version of our plugin.
Let me know if this works our for you.
All the best,
Eva
