Boycott AP! Crucify Mike! hehe man you gotta fight for your right! Just kidding.
Pero seriously, AP is not the only one offering such after sales service and its not bad after all. If you buy appliances (ref, tv, dvd players, ACs, electric fans, name it), you'll have to bring them to their nearest service center yourself if it gets busted. For the companies, its a matter of business economics. For us, its a matter of preference. Choose stores that you think will provide you with the your own expected level of after sales service.
To be honest, I hesitate to buy from AP bec. their service center is in Marikina which is far from where I live (petrol is not cheap nowadays!). I only buy gator cases from them because no other store is carrying them. But now I saw Yamaha have gator cases which has 3 or 4 branches/sister company so its a convenience for me. On another note, the guys in AP Alabang and Mang Bert (ata name nya) from Paco are better salesmen than other branches.
