yo locksley,
check this out
http://www.full-stop.com.sg/
its $320 excl gst. free delivery to doorstep.
a while back apple sg was doing a price match. but dunno if its still available. basically u ring them and tell them u can get it at a cheaper price. refer them to the website and they will verify. then if they think they can match it, they'll call u back. and deliver it. if u wanna save the hassle then just order from fullstop.
hope it helps, welcome to the cool world of Nano!!!!
