Where Is My Order
Where do you ship?
We currently ship within the lower 48 United States, including P.O. boxes and APO/FPO addresses. We do not currently ship to Alaska, Hawaii, U.S. territories, or destinations outside the United States.
Why hasn't my order shipped yet?
Orders ship within two (2) to three (3) business days of being placed, Monday through Friday.
During a high-volume sale period, please allow up to three (3) additional business days for processing.
Where is my order? It shipped, but I still haven't received it.
Delivery estimates are estimates only and depend on the carrier. Carrier transportation delays, including delays caused by weather or natural disasters, can occur.
If you have received tracking information, check the carrier's website for the latest status.
Where can I find the status of my order?
You'll receive an order-confirmation email and a shipping-confirmation email with tracking information. Once your order is with the carrier, track it using the link in your shipping confirmation email and on the carrier's website.
Why does it say my order is "unfulfilled"?
Confirmed orders remain in an unfulfilled status until they have been packed and released to the carrier.
Can I cancel, change my address, or edit my order?
If your order has just been placed and has not shipped, our JYM Service team may be able to help. Please act quickly. Once an order has been released to the warehouse for processing, we cannot cancel it or make edits, including address corrections.
After that point, any address change must be made with the shipping provider once tracking is available, at your cost.
My package says "delivered" but I can't find it. What now?
Please wait 24 hours before contacting us. Packages are sometimes scanned as delivered early, and delivery is often completed within the next 24 to 48 hours.
If the shipment was sent by USPS, check your mailbox and parcel locker. If it was sent by UPS, check all entrances and nearby areas. If you still cannot locate it, email customerservice@jymsupps.com.
Do you offer expedited shipping?
We do not currently offer expedited shipping. If expedited options become available in the future, the applicable methods and charges will be shown at checkout.
