Unfortunately due to our return policy #11 on our terms of use page we can't offer refunds. Also this isn't an issue with our templates but a 3rd party extension that you can use with this template, VirtueMart. But you can use a different shopping cart too. Like on our GCK Store we show Virtuemart and also Hikashop, perhaps try Hikashop?
