Is Honey Bunches of Oats legit?

Legit

Honey Bunches of Oats is the genuine article: a Post cereal of flakes and crunchy oat clusters on shelves across the US. If a box lets you down, it is usually freshness or something odd in the bag, and the code printed on the box is what ties that box to its batch.

What we checked

  • On grocery shelves since 1989
  • Made by Post Consumer Brands
  • Maker based in Lakeville, Minnesota

Watch out for

  • A nut allergy at home, since some Honey Bunches of Oats varieties contain almonds or pecans.
  • Something hard or sharp found in the cereal, where the best-by code on the box shows which production run it came from.
  • A box with fewer clusters or almonds than you expected, which a photo of a bowl beside the box helps show.

Stale clusters in a box you just opened?

We help you write it, it gets its own public page, and you can have it sent to Honey Bunches of Oats as a formal letter.
