There is no apple store. Apple website links to several agents, but states "price and terms will vary". Got quote from some of those agents, one of which replied as you will have to pay $50 for assessment, then they will tell you how much. Another agent names Uxxxxxx quoted $300-570 depends on whether they have the ability to open your iPhone 5s. Others quoted as $130-160. (US and China official price is NZD116 and 133 respectively)
Any thoughts?
