for increased cost due to postage, people gotta look at it this way :
if you live near roxy square 2 (which I do) then no point paying for registered postage.
come on over and pick it up yourself.
if you live far away above 5 bus stops range. you might as well pay for registered postage to get it straight from your doorstep at your convenience than take bus..take mrt...change bus... walk walk walk. and collect cd... take bus back etc. and easily hit above $3 worth of transport and an hour of your precious life's time.
if postage gets too much due to the load of cds that you're purchasing. remember that one big envelope can store multiple cds. so buy one bulk (of local cds

) at one shot and it'll be worth your money.
