I bought 2 packets of kaseidon or rice topped up with cubes of sashimi (raw fish) at 50% discount from a supermarket near our home. The original price was 399 Yen each but after discount it was 199 Yen or the equivalent of S$2.70 each. The food is discounted from 7 pm each evening. The food is fresh and when refrigerated it can be eaten even after a few days. I use to pay S$12.90 for the same amount but less fresh at Sushiro in SG.
