Change currency via URL?

Is it possible to have the currency changed without hard coding something, like having a adder to the url to change the currency?

thanks

Yes. That's how the currency-selection sidebox works presently.

Can you tell what the url looks like as mine does not change
looks like domainname.com/shop/index.php?main_page=index before and after i change currencies.
I was thinking that it should have a reference to currency=GB or something when selecting GB as currency.
Or am i off on a tangent here?

thanks

Simply adding &currency=GBP will change the store into that currency, for that customer's shopping session.

After set, the URL will NOT continue to show it, since it's not needed in the URL once set. The prices, however, will be showing in the new currency, until logoff or closing the browser, or until selecting another currency.
