Judebabe,
the last i knew was the following places... but not sure if still valid:
cold storage (parkway, great world city, bugis)
carrefour (never state which outlet, but it's near the bread section)
Jurong Point 2 outside NTUC X'tra there's a counter selling all kinds of nuts and dried fruits
Giant at Vivocity (raw brazil nuts with shell)
hope this helps. and for your info, KKH now provides 14 days of HL for a start. think there's a change in standard/policy.
wish u success too...jia you!
