Back in June, Oreo announced they'd be running another MYSTERY FLAVOR promotion. They did it a few years ago, and everyone immediately knewthe flavor was Fruity Pebbles, which tasted GROSS between chocolate cookies.
Well . . . Oreo just announced the new mystery flavor will hit stores on Monday.
And if you guess it correctly at MysteryOreo.com, you'll be entered to win $50,000.
