1 Year Limited Warranty registration is a pain when you purchase with RWM or any unauthorised reseller. Got to ring the Apple line. Amercian staff ask you to read out your serial number, ask you to scan and send the RWM handwriten paper invoice. After verification and entering the registration date. The american inverted DD/MM/YYYY with MM/DD/YYYY. Ended up 12 month warranty have shrunk to 4 month warranty. Called up again, pinoy staff picked up, apologised and date is changed to the correct date. From there, you can purchase AC+.
Whereas if you were to purchase direct from the Apple Store, the 1 Year Limited Warranty will be automatically registered. If you opt for AC+ upon checkout, that's automatic too. Hassle free.
But is it worth the trouble for $50 savings? I would say yes. Worth it.
