Being an independent bookseller is tough. Couple years ago, it was BooksActually in danger of losing its lease. This time is the much newer Booktique.
In an announcement on Facebook, the founder, Anthony Koh Waugh states that sales haven't been up since November (due to the poor economy, duh), so here's what you can do: go buy a book or get gift vouchers ($20, $50 and $100 ones are available) and ask to rent the back room for workshops. If you can buy the books in bulk, even better. The store is located at Citylink Mall's B1-17. You'll be able to find work by local writers, lots of books on how to publish and a some coffee table books, too.
Email Anthony here to purchase vouchers and find out how to rent the back room here.
