I thought the main issue with getting applecare from 'unauthorize' seller is fact that the same applecare code might be reuse/resold, in which apple will require proof of purchase and box to authenticate the 'real' buyer.
Yes that's what I have verified with Apple too. In fact with regards to lower pricing of APP, I have escalate all the way up to Apple a few days back. Asking to the highest level handling APP. They are also quite helpless to the situation.
So it seems there is possibility that these lower cost APP are due to selling of unclaimed APP. That means suppose if I sold APP to some uneducated consumer and they didn't claim it online, or those unlucky fellas got scam by it. I can potentially sell legit APP to those at a lower price, not that I must, but it will looks good on the public.
The whole cycle is funny. APPLE will not be that stupid to sell a piece of service that THEY THEMSELVES is the PRIME and need to provide the service out of their own pocket at a lower price to another tier of retail and then sell them cheaper. Obviously the consumers will buy from the cheaper source, but WHO is producing the labour to provide the service ? APPLE SERVICE CENTRE
I am skeptical the registration code can be easily cracked since it has to naturally come 1-to-1 authenticated against Apple support database.
Hence I'm inclined to believe when you get a cheaper APP, someone or a few of someone have fallen victim to the scam done by the same vendor you are getting the APP from, or they are in fact the 3rd tier retail that got it from the black market that sells to them.
