I'm going to Singapore this September for the F1 race and i'm also thinking of getting an MBA 2011 there. I have already asked our local retailers here for their discounted prices but i still want to know if I could get a better deal in Singapore after GST refund and other deals. Would anyone know the best and cheapest shop I could get the MBA in Singapore? Would shops have different deals e.g free case/sleeve/etc.? Thanks in advance!
