When I go to checkout page after adding some product in my cart and then fill billing and shipping form then Total table shows me shipping tax based on shipping address.
But when I reload or refresh the checkout page the info of billinng and shipping form has gone but tax amount (calculated before refreshing the page) is still showing in Total review table. I want to set it to zero. I have applied below code but did not work-
$shippingaddress = Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress(); $shippingaddress->setTaxAmount(0); $shippingaddress->save();
this code set tax Amount to '0.00' in review table on page loading for a while but when page is fully loaded then this tax amount is replaced by old tax amount. But I want it to remain '0.00'. How I can do that.?
