Oreo O’s have officially been discontinued by Post after almost thirty years. Introduced here in the states in 1997, this isn’t the first time we’ve said goodbye to this cereal. In 2007, it was cancelled and then brought back in 2017 in a permanent capacity. Now, Oreo O’s have been replaced by Oreo Puffs, a similar offering with marshmallows, sure, but is it really enough to warrant such a big change? How do you feel about the loss of Oreo O’s? #foodstagram #oreo #breakfast #cereal #snacks | sna
