Marketplace Policy

DELIVERY & SHIPPING
  • Due to the nature of our marketplace and the majority of our products coming from independent sellers and vendors, each delivery window and shipping fee will vary from seller to seller. The "Estimated Delivery" dates on each product page represents the delivery window for that specific product. With this in mind, the below provides an average delivery time across the Apollo Marketplace.
  • Continental U.S. delivery time - 2-5 days
  • Canada delivery time - 7-10 days
  • International delivery time - 7-14 business days
SHIPPING COSTS

Upon finalizing your purchase, the shipping fees are calculated by aggregating the individual rates set by each seller for their products. For instance, if one of your selected items has a shipping fee of $5 from Seller 1, and another item incurs a $6 charge from Seller 2, your combined shipping total at checkout will be $11. However, should your order from any individual seller meet their stipulated free shipping threshold, the shipping fee attributed to that seller's items will be waived, therefore reducing your overall shipping costs at the time of checkout.

RETURNS

Each seller and vendor has a unique policy as it pertains to their business and products. Because of this, each shipping and return policy will be mentioned under the Seller's Policy tab on the product page. Unless specifically stated under the Seller's Policy tab, original shipping costs are not refunded. Please review our Returns & Exchanges tab for policy details or for more information reach out to support@apollolanding.com

About the Seller

HISTORY OF THE BRILLIANTK9 HARNESSES

As lifelong dog enthusiasts who have owned and trained rescue dogs of all shapes and sizes, we found a need for an effective, better designed, higher quality, product that promotes the health and safety of the dog. Whether they are top performance dogs, or just your best friend lying on the couch beside you, they deserve a harness that functions properly.

Dissatisfied with existing dog walking equipment, we consulted veterinarians, veterinary chiropractors, canine massage therapists, rehabilitation specialists, professional dog trainers, and our friends in the dog community as to what would be a more effective and ergonomic dog walking tool.

Based on our fact finding, we set out to design a harness that was ergonomically superior to anything on the market and that would not encourage the dog’s natural opposition reflex to drive their head down and pull. It also was designed to allow the dog to run, sit, swim, play, and compete in sporting events with comfort and without restraint of natural movement.

Our companion animal’s health is as important as our own and our mission is to provide you with the most ergonomic, comfortable, effective and safe product on the market. We are also proud that every BrilliantK9 dog harness is made in Lucas, Ohio.
