Because My American Goods works with many independent American brands

Shipping details
What is processing time?
Processing time is the period between placing your order and the package being handed to the shipping carrier.
Most orders are processed within 2–5 business days, Monday–Friday excluding holidays.
During this time, your item may be picked, prepared, produced, finished, assembled, personalized, packed, or otherwise made ready for shipment.
Shipping time does not include processing time. Carrier transit begins after processing is complete and the package has been accepted for shipment.
Where does my order ship from?
My American Goods® uses a hybrid fulfillment model.
- Some products are stocked and shipped directly by My American Goods.
- Other products ship directly from the independent American brand or maker.
This allows us to offer a much broader selection of American-made products while supporting the independent businesses that make them.
Why might my order arrive in multiple packages?
Products in the same order may ship from different fulfillment locations.
As a result, items may:
- Ship on different days
- Arrive in separate packages
- Have different tracking numbers
- Use different shipping carriers or services
Receiving one package does not necessarily mean the rest of your order is missing.
How are shipping rates calculated?
Because products may ship from different makers and fulfillment locations, shipping rates can vary by product or brand.
- Some products or brands qualify for free shipping above a specific threshold.
- Other products may use flat-rate or carrier-calculated shipping.
- Products shipping from separate locations may generate separate shipping charges.
The applicable shipping cost is shown before your order is completed.
When will I receive tracking?
Tracking information is emailed once your item has been prepared and shipped.
For handmade, made-to-order, pre-order, or specialty products, tracking may not be available until the applicable preparation or production period is complete.
If the expected processing period for your item has passed and you have not received a shipping update, please contact us.
Carrier delays & missing packages
After a package has been accepted by USPS, UPS, FedEx, or another shipping carrier, transit may be affected by weather, holidays, peak-volume periods, transportation disruptions, or other carrier conditions outside our control.
Shipping and delivery timelines are estimates unless expressly stated otherwise.
If tracking shows Delivered but you cannot locate the package, check:
- Household members
- Neighbors
- Porches, side doors, garages, and other delivery areas
- Parcel lockers or building mailrooms
Carrier scans can occasionally appear shortly before final delivery. If the package still cannot be located, we can assist with a carrier investigation.
Shipping address accuracy
Please review your shipping address carefully before completing your order.
Customers are responsible for providing a complete and accurate delivery address.
Packages returned because of an incorrect, incomplete, or undeliverable address may require additional shipping charges before they can be sent again.
