From Changi website:
Sounds like a great deal, of little use to me as I rarely transit my home airport (sometimes do on separate tix), but I am sure may be of interest to some AFF'ers.
Singapore Airlines and SilkAir customers transiting in Singapore have more to look forward to with the enhancement of the recently introduced Changi Transit Programme. For a limited period from now until 30 June 2013, eligible customers will receive $40 worth of Changi Dollar Vouchers (CDVs) per ticket – double the amount since the Changi Transit Programme began on 1 October 2012.
To qualify for the CDVs, customers must travel on Singapore Airlines or SilkAir on both their inbound and outbound flights, with a 13-digit e-ticket receipt number beginning with 618 or 629.
The CDVs are valid for one-time use at more than 450 retail, food and service outlets in the transit and public areas of Terminals 1, 2 and 3, excluding outlets in the Arrival Baggage Claim Halls. They can also be redeemed for one-time access to the Ambassador Transit Lounge at Terminals 2 and 3 for up to six hours.
