I was looking for the piece of paper I used to write down the prices of some encores I asked but I couldn't find them now. :( Give me time until tomorrow to look for them and I'll get back to you. The only items I remember are the ones that I bought. Henkei Deluxes cost me SG$30 each and the commemorative soundwave is SG$50 (it was tagged for $60 but the seller gave it to me for SG$50). Regarding your holiday trip, I also would like to know coz my visit there last month is only a 10hr-stopover. Just enough time to roam the city during the day. Buy an umbrella, sometimes it seems the rain won't stop. :)
Note that 1SGD is almost equivalent now to 1AUD.
