I need following modifications of Virtumert:
1. Shipping modification to add free shipping functionality as described in the attachment
2. Currency modification: if a customer chooses to display different than default currency, then everything will be displayed in 2 currencies: browse page, detail page, basket, all checkout, invoice, confirmation e-mail. However the payment will be done in the default currency independently on the payment method.
Please in case of any doubts, contact me.
