I just tried the Costco raisin bran for the first time, and it is so much better! The flakes are thicker and crunchier, and the raisins aren't encrusted with sugar. The regular Post raisin bran is flavorless and gets all mushy as soon as you pour the milk in, and the little stale raisins are sugar bombs, meaning that the regular raisin bran has more sugar in it than many "sugar cereals." And the flavorless flakes - it's like they sweep up the floor after they're finished making a good cereal and just smush that into flakes. The Costco raisin bran flakes have a hearty bran taste somewhere between Wheaties and Product 19. The Costco raisin bran tastes just like a bran muffin with raisins in it, and stays crunchy to the end. I'll be buying it again.
