very tiring to get a response from Iprice, shipping to Penang 11100, I'm seeking Homocysteine Modulators. the site seems to jump over to N Zealand where shipping is mentioned by DHL also customes duty to be paid on entering Malaysia. Having previously had many problems with Malaysian Customs I'd appreciate what cost the duty might Be. I'm resident in Penang on MM2H 10 visa.
