Similar to the deal last time but now extended until the end of the year. Valid for Singapore Airlines customers excluding codeshare passengers.
Now restricted to travelling from 16 countries (including Australia), so if you are going elsewhere you must claim on your outbound leg. Singapore must not be your starting or final destination. Because of the fall of the Aussie dollar, the deal is now worth ~$4 more than a few months ago :P
The place to claim is now at the "iShop online booth" as opposed to the information counter. Similar terms and conditions as before, vouchers are stackable.
Terms & Conditions
1. Only effective for tickets issued on 01 October 2012 – 31 December 2013, both dates inclusive.
2. Only effective for transit passengers whose departure date from point of origin is between 01 January 2013 and 31 December 2013, both dates inclusive.
3. S$40 Changi Dollar Vouchers are valid from date of issue to 31 March 2014.
4. A S$40 Changi Dollar Voucher may only be claimed once for each ticket issued, either on the outgoing or the return leg of the itinerary.
5. Multiple vouchers may be used for payment.
6. Vouchers may not be used with ongoing in-store promotions.
7. Vouchers can be used in conjunction with Singapore Airlines Boarding Pass Privileges.
PS. Can't update the previous deal so I thought I should post this separately.
Transited last time but they ran out of voucher, gave them my details but no follow up after
