i think ordering online is the best option for original ps3 games.& play asia is the best as they offer free shipping to bd.other ways are little bit complicated.as u may not find the game u r looking 4 in those gaming shops in dhaka.& u have to be lucky to apply the 2nd method ! but in this case,i’m very lucky,cus i’ve got a lot of relatives who lives abroad ! & most of them lives in USA !
not the best option in my opinion though sorry.
SM Malls, Ayala Malls, even satellite stores sell original games. Going to the mall won't take days to do. No money conversions involved. No account management and other online processing. Faster than Fedex.
