We have purchased and installed the 'storefront VirtueMart template' at http://samsungwater.playtimedm.com.
However, when we tried to make a purchase and go through the checkout process we found an issue. When we try to add different Ship To Address than Billing Address, for GUEST checkout, the newly added Ship To address is overridden by the Billing address.
Also, when the Checkout button is clicked, the Ship To address is completely removed and doesn't appear on Order Confirmation page.
We tried with a fresh copy of your Quick Start installation and the issue was still there. There is no such an issue on your template demo site though - https://demo.gavick.com/joomla25/storefront/
Any help you could give us would be great. We are on Joomla 3.4.1 and VirtueMart 3.0.6.2
Thanks
Paul
