Hello Cissy, do you just want to buy this accessory separately? If so, the unit price will be high (because of the shipping cost), since you are in Hong Kong, too, so we can accept the local bank transfers, please submit ticket (with product link & request) to our Support Center and let my teammate helps you directly.  n_n

Hello Cissy, we accept online orders pay by credit cards, debit cards, prepaid cards, gift cards & Paypal, and bank transfer via Skrill(Moneybookers) & Western Union.  n_n
