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
