Hah, I try to use coupons for Domino's orders aswell, but it seems I'm not taking it far enough! What a challenge for next time :D
Also, that sushi looks delicious! We tend to go out for sushi. Last time, we had sushi for lunch in Zwolle, because it costs less than dinner time and still tastes great :-)
It's fun stacking coupons. you can easily search for them online. Sushi for lunch...never thought about it but I can see that working.
