TS, i think you are the one who is being complicated here. If u want to compare prices, convert them either all to usd or sgd. It will be easier for you to judge which is more expensive to buy in singapore or in US. The problem with this thread is you are not comparing apple(sgd) to apple(sgd) but instead apple(sgd) to orange(usd). Then you start making a fuss of people not understanding you... Furthermore, start using improper and shortcuts english, with a hint of childishness in your replies.
I am not here to argue, just giving my thoughts when people here are trying to help you see things but you are kicking a big fuss of people not understanding what you are trying to bring across.
Cheers.
