You are probably best off shipping your own parcels instead of letting shop owners do this for you, both to save money and to ensure that you are actually shipping what you purchased and not a quick substitute—though most shop owners are honest and won't try to cheat you in this way. The workers at Hong Kong Post are extremely friendly, and will sell you all the packaging equipment you need, at unbelievably reasonable prices. Large international couriers in Hong Kong include DHL and Federal Express.
