I have no problem finding them in Bugis Street. There's many to choose from, each with their own unique personality. Of course, they come with a price too. I prefer cheaper ones, coz they r more affodable. And I wouldn't feel the pinch if I were to discard them, for watever reasons. :P
In fact, there's TWO that called out to me today, telling me to bring them home and promise to make me happy. $10 each. Goodness! How can I resist such temptations?!
