I love your oatmeal! Can I buy it from a grocery store? June 06, 2019 01:10 Updated No, our oatmeal is made specifically for Peet's by a private manufacturer and cannot be purchased anywhere else but Peet's! Related articles I purchased a muffin at Peet's while on vacation, but it is not offered at my local Peet's, why? Who makes your sauces and syrups? How fresh are you pastries? Can I buy my breakfast sandwich cold and heat it myself at home? How fresh is the coffee that is served?
