Free Economy Shipping — USPS Large Envelope
This is the no-cost shipping choice. Orders are sent as USPS First-Class Mail large-envelope/flats service when the item qualifies.
Estimated transit: 6–8 business days after dispatch. Fahmah Jackson normally dispatches paid orders within 1 business day, Monday–Friday, from Chester, New Hampshire.
Tracking: Economy large-envelope mail does not use normal USPS package tracking. Visibility updates are provided through USPS Informed Visibility and Fahmah Jackson's First Class Track service. These events can show mail-processing progress, but this service may not provide the same acceptance or delivery scan that a USPS parcel receives.
If you need standard USPS package tracking and a delivery scan, select USPS Ground Advantage or USPS Priority Mail.
Orders totaling $25 or more may be upgraded to USPS Ground Advantage at no additional charge when eligible. Orders sent to a freight forwarder must use Ground Advantage or Priority Mail.
If an economy shipment appears lost or arrives damaged, contact Fahmah Jackson directly so we can review the shipment and arrange an appropriate refund or replacement.
USPS Ground Advantage
USPS Ground Advantage is the recommended tracked parcel service. It is also the minimum service required for freight-forwarder orders.
Estimated transit: 2–4 calendar days after dispatch. Fahmah Jackson normally dispatches paid orders within 1 business day, Monday–Friday, from Chester, New Hampshire.
Tracking: Ground Advantage uses standard USPS package tracking. The USPS tracking number can be followed on the normal USPS tracking system and is intended to provide parcel acceptance, in-transit, and delivery-event visibility as USPS scans the package.
This is the better choice when you need a conventional USPS tracking number, delivery scan, freight-forwarder compatibility, or stronger shipment visibility than Economy Large Envelope service.
If a tracked parcel is delayed, lost, or damaged, contact Fahmah Jackson directly with the order information and we will review the USPS tracking record and resolve the shipment as appropriate.
USPS Priority Mail
USPS Priority Mail is the expedited tracked parcel choice.
Displayed transit estimate: 2–4 calendar days after dispatch. Actual USPS transit can vary by destination and operating conditions. Fahmah Jackson normally dispatches paid orders within 1 business day, Monday–Friday, from Chester, New Hampshire.
Tracking: Priority Mail includes a standard USPS package tracking number for use on the normal USPS tracking system, with USPS acceptance, in-transit, and delivery-event visibility as scans are recorded.
Select Priority Mail when faster USPS parcel handling and conventional package tracking are more important than the lowest shipping cost.
If a Priority Mail shipment is delayed, lost, or damaged, contact Fahmah Jackson directly with the order information and we will review the USPS tracking record and resolve the shipment as appropriate.
Returns
We want you to be satisfied with your purchase. If an item is not right for you, contact Fahmah Jackson within 30 days of the purchase date to arrange a return.
Unless the item arrived damaged, defective, or materially different from the listing, the buyer is responsible for return shipping. Items should be returned in the same condition received, with original packaging and included parts when reasonably possible.
After the returned item is received and inspected, the appropriate refund or replacement will be processed. Original shipping upgrades or other non-refundable carrier charges may be excluded from the refund when applicable.
Please include enough information with the return to identify your order, such as the order number, purchaser name, or a copy of the order confirmation. Do not send a return to an unrelated marketplace address.
