There's a lot of leftover merchandise from the Singapore Biennale, and it's selling at a mad 70% discount. I got a Barbara Kruger t-shirt at just $6 (If you'd gotten it during the Biennale, you'd have shelled out $20).

There're also tonnes of free badges left over from the contest (free badges were available at each Biennale venue, and if you managed to collect all 95 designs you could've won some Pioneer loot).
Just head over to the Biennale office on the 5th floor of The Adelphi, open Mondays to Fridays, 10am to 6pm. Bring cash.
