This evening at the local fresh produce store in Gakuentoshi (where I live), there was a sale on all their huge sushi boxes which were all half price!
This place already sells their sushi and fresh fish fairly cheap, but 500円 for 18 pieces is a ridiculously good deal!
Also considering their sushi is much better than the sub-par stuff you find at Daiei, at 500円 it was a quarter of the usual price for a box that size!!
Needless to say tonight I dine like a shogun!
Edit: Several weeks down the track I have discovered this discount is a weekly occurrence, and so Wednesday is now ‘Sushi Night’ （＾∇＾）
