I played the Kikkoman Instant Win Game and I just found out that anyone who plays wins something. There are tongs, basting tools, cookbooks, spoon rests, even coupons.
Go to their website, request a pin, and after you receive it in your email, type it in to the appropriate box and see what you won!
Good luck, everyone! Leave me a comment later and let me know what you won - I would love to hear what you all are getting!
Thanks, Surviving the Stores, for the tip!
