other from warranty, buying PS4 oversea and ship to Malaysia, your PS4 will get hold by Malaysia Custom
they will ask you to go to Sirim office to get approval and sticker (which need pay for application)
then will need pay gst at Malaysia custom if you want collect your PS4

know this info from friends who bought PS4 from ebay/amazon and sending from oversea to malaysia

this i not very sure
but not sure if it is still cheaper than buying locally after paying sirim and custom for gst + delivery fee
this only apply on electronic item
but problem is you need take leave, drive all the way to custom office do the stuff, and go to sirim apply for the item. kinda waste time for only buying 1 item.
except it is still cheap after all this, then ok la~
