Fulfillment by Amazon MCF
All orders shipped within the United States are fulfilled through Amazon Multi-Channel Fulfillment (MCF). Amazon picks, packs, and ships your order from a U.S. fulfillment center, with tracking updates powered by Amazon's logistics network.
Shipping methods & delivery times
Delivery times follow Amazon MCF's official fulfillment schedule, counting from the date your order ships (not the date you place it):
| Method | Delivery Time (business days) | Cost |
|---|---|---|
| Standard Shipping | 3–5 business days | Calculated at checkout |
| Expedited Shipping | 2 business days | Calculated at checkout |
| Priority Shipping | 1 business day | Calculated at checkout |
Actual delivery time may vary depending on your location, carrier conditions, and seasonal volume. For the most accurate estimate, refer to the tracking details provided by Amazon once your order ships.
Order tracking
Once your order ships via Amazon MCF, we'll send a confirmation email with a tracking number. You can follow your package's journey at any time from that email, with real-time updates from Amazon's fulfillment network.
