the prices are in USD...singapore is not the centre of the world yet, so most countries won't choose to list using SGD. maybe in another 10-15 years? hehe
yes i bought truckloads of stuff from dx. its damn cool lah. got a 6-inch ceramic kitchen knife so US$15 when stores are selling at 70-80, and there's also the motorola h700 bluetooth headset that goes for about $100 in stores for only US$15.
oh, i didnt know topics in kopitiam must be photography related as well. like that nothing much to talk about already...
