If you want a customer to pay with a different currency from the default one, simply append this to the URL:

?currency=cad

Example:

https://www.clientexec.com/members/order.php?currency=cad

In this example, cad is the Canadian currency. You can change the three letter ISO code to whichever currency you would like. 

To find what ISO codes you currently have configured, go to:

Setup -> Billing -> Currencies

The ISO codes are under Code.
