Trigger Identifiers (Selected Currency)

Hi Guys,

We are looking for a plugin to manage the currency switching and this plugin seems to fit the bill so far. I do however have a question about possible hooks or triggers. We have an in-house plugin that handles VAT exemption users. Outside of the UK this is not necessary and so I was wondering whether you had built in hooks that I can query to determine if the currency is set to anything other than GBP. This would make for a perfect trigger to hide my VAT exemption form. I can do this based on location, and based on billing address but typically if they deny location services, that means the VAT form would be shown before they have a chance to add their billing address and thus, it would be too late.

IF there is something like this, or perhaps a way I can retrieve the current currency based on the current session, I would appreciate it.

Regards
Kane
