That is because apple store sells 32gb space grey at $1148, in the Mobile Phones Bazaar HWZ section, people are selling brand new 32gb space grey sets at around $1050 to $1080.
Hence, you are paying extra $70 to $102 more for apple store set.
For me abit kanchiong, is because i used debit card (linked to bank account) for apple store purchase, and my original plan is to top-up the bank account linked to debit card on 1st October, if they already start deducting from my card 29 or 30 Sept, the deduction will fail.
