Everything you need to know about your favorite southern secret ingredient, shipping policies, and more.
What makes Duke's Real Mayonnaise different from other brands?
Duke's is famous for being the only major mayonnaise brand that contains no added sugar. This gives it a unique, tangy flavor profile often referred to as the 'Southern Secret' that has been a staple in kitchens since 1917.
How should I store my Duke's products?
Unopened jars should be stored in a cool, dry place like a pantry. Once opened, Duke's Mayonnaise must be refrigerated to maintain its quality and freshness. Do not freeze, as this will cause the emulsion to break.
Do you offer international shipping?
Currently, we only ship our products within the United States and Canada. We are working on expanding our shipping capabilities to bring Duke's to fans worldwide in the future.
Are Duke's products gluten-free and Kosher?
Yes, Duke's Real Mayonnaise is naturally gluten-free and is certified Kosher. Please check the specific label on our specialty sauces and dressings for individual dietary certifications.
What is your return policy for food items?
Due to the perishable nature of our products, we cannot accept returns. However, if your order arrives damaged or if there is an error in your shipment, please contact our customer service team within 14 days for a replacement or refund.
How can I track my order?
Once your order has been processed and shipped, you will receive a confirmation email containing a tracking number and a link to the carrier's website so you can monitor its progress.
