Buy any Kikkoman Sauce 10 oz+ and get a FREE 10 oz Ponzu (Max. Value $3, expires 30 days from printing)
I was able to print two from one computer.
A passage from the link:
"Ponzu is excellent as a dipping sauce or marinade. Fish, meat, and tofu all benefit from marination in ponzu, and are delicious grilled. As a dipping sauce, ponzu goes well with a wide variety of sushi dishes, spring rolls, and tempura vegetables, along with various plain grilled foods. Many Japanese restaurants also serve ponzu along with other dipping sauces in accompaniment to traditional hot pot dishes for a casual meal which combines a multitude of delicious and fun flavors."
