All shipping on BullionStackers is handled by the seller — the platform never ships items or handles shipping costs directly. The seller is the merchant of record for every shipment.
Shipping is currently limited to USPS domestic services only (United States). International shipping and multi-carrier support are planned for future versions.
Shipping costs to the buyer are always fixed-rate, set by the seller on each listing. Sellers configure:
Sellers can enable a signature-required option on their listings. This adds a flat fee per shipment (not per item). When enabled, USPS will require a signature at delivery.
After payment is confirmed, the seller ships the order using one of two methods:
The seller sets up a Shippo sub-account linked to BullionStackers. After payment confirmation, the seller enters package details and generates a prepaid USPS shipping label directly within the app. The tracking number is populated automatically. The seller pays the actual Shippo rate through their sub-account — this may differ from what the buyer was charged.
The seller handles shipping entirely on their own using any USPS account. After shipping, the seller manually enters the USPS tracking number in the app. The platform looks up the tracking status via the USPS API and displays the tracking history on-site, sending notifications when the status changes.
Regardless of fulfillment method, BullionStackers tracks every shipment via USPS. Both buyer and seller see real-time tracking updates on the order detail page, including: label created, accepted by USPS, in transit, delivery exceptions, and delivered.
Delivery Protection ("Delivery Protection") is an optional coverage offered on eligible orders that reimburses an at-risk party if a package cannot be confirmed as delivered by the United States Postal Service ("USPS"). Delivery Protection is offered to buyers in the standard pay-first flow and to sellers in the reverse (pay-on-arrival) flow when the seller opts in at listing time.
Coverage begins when USPS records the first acceptance scan on the package and ends when USPS records a "Delivered" status. Once USPS marks the package Delivered, BullionStackers' liability under Delivery Protection ends, regardless of what happens to the package thereafter.
The 14- and 21-day windows are admin-configurable in Platform Settings.
A claim becomes filable from the order detail page once the order's tracking window has expired without a USPS Delivered confirmation. The eligible filer is the buyer in the standard flow and the seller in the reverse flow.
The claim form collects shipment details (auto-populated from the order and USPS tracking), a reason from a fixed dropdown, optional comments, three required confirmations, and optional supporting documentation. Claims are reviewed by BullionStackers administrators against USPS tracking data, transaction history, and account activity. False or coordinated claims may result in account suspension or permanent removal from the platform.
Claims resolve to one of two states: Paid (the platform reimburses the filing party for item value plus shipping) or Denied. Both states require mandatory administrator notes recorded for audit. Payouts are processed offline by the BullionStackers operations team; the admin panel records the decision and the dollar amount paid out for the audit log.
The Delivery Protection fee is calculated as a percentage of the order's item subtotal (excluding shipping, signature, and any other add-ons). At the time of writing the fee is 1.75% on orders under $1,001 and 1.50% on orders in the $1,001–$5,000 range. The percentages and the eligibility cap are admin-configurable.
Buyer-paid Delivery Protection fees in the standard flow flow to the seller at order placement and are non-refundable. The seller's monthly Stripe invoice from BullionStackers includes a separate Delivery Protection line-item section that sweeps the seller-paid reverse-flow Delivery Protection fees accrued at SHIPPED.
BullionStackers may amend these terms from time to time. Material changes will be surfaced in-app and via email; continued use of the platform after a change constitutes acceptance of the revised terms.
