Marketplace Terms
Additional terms governing buying and selling on Grail Den
Effective: March 1, 2026
These Marketplace Terms of Service ("Marketplace Terms") supplement the Grail Den Terms of Service and govern your use of the Grail Den Marketplace ("Marketplace"), a feature that enables registered users to buy and sell collectibles, memorabilia, and related items. By listing an item for sale or purchasing an item through the Marketplace, you agree to be bound by these Marketplace Terms in addition to the general Terms of Service and Privacy Policy.
If there is a conflict between these Marketplace Terms and the general Terms of Service, these Marketplace Terms control with respect to Marketplace transactions.
Table of Contents
1. Platform, Not Party
Grail Den operates as a marketplace platform that connects buyers and sellers of collectibles. Grail Den is not a party to any transaction between buyers and sellers. We do not take title to, possess, inspect, authenticate, appraise, store, or ship any items listed on the Marketplace.
When a buyer purchases an item from a seller through the Marketplace, the transaction is solely between the buyer and the seller. Grail Den acts only as an intermediary that provides the technology and platform to facilitate these transactions.
Grail Den does not guarantee the identity, reputation, or creditworthiness of any buyer or seller. Users are responsible for conducting their own due diligence before entering into any transaction.
Back to top2. Fees & Fee Disclosure
The Marketplace charges a 7.5% Buyer Protection Fee on every completed transaction. This fee is added to the item's sale price at checkout and is paid by the buyer.
| Party | What They Pay | What They Receive |
|---|---|---|
| Buyer | Item price + 7.5% buyer protection fee + shipping | The item, buyer protection coverage |
| Seller | No platform fees deducted | Full listed sale price (minus Stripe processing) |
Stripe payment processing fees (currently 2.9% + $0.30 per transaction) are standard third-party charges and are separate from the Grail Den Buyer Protection Fee. The seller receives the full listed sale price minus Stripe's standard processing fees.
The Buyer Protection Fee is non-refundable except in cases of legitimate disputes resolved in the buyer's favor (see Section 8: Dispute Resolution).
Grail Den reserves the right to modify its fee structure with thirty (30) days' notice to active users. Transactions initiated before a fee change takes effect will be processed under the prior fee structure.
Back to top3. Payment Processing
All payments on the Marketplace are processed by Stripe, Inc., a PCI-DSS Level 1 certified payment processor. Grail Den does not directly process, store, transmit, or have access to your full payment card information.
By using the Marketplace, you also agree to Stripe's Terms of Service and Stripe's Privacy Policy.
Seller payouts are processed manually by Grail Den after successful delivery confirmation. Grail Den does not operate an escrow service. Payout timelines may vary, and Grail Den reserves the right to hold funds pending resolution of disputes, chargebacks, or suspected policy violations.
Back to top4. Seller Responsibilities
By listing an item for sale on the Marketplace, you represent and warrant that:
- Accurate descriptions: All item descriptions, condition notes, provenance claims, and other listing details are truthful, accurate, and not misleading.
- Real images: All photographs are of the actual item being sold (not stock photos, representative images, or images of different items), taken by you or with your authorization.
- Legal ownership: You have clear legal title to the item and full authority to sell it. The item is not stolen, encumbered by liens, or subject to any legal claims.
- Shipping timeline: You will ship the item within five (5) business days of receiving payment confirmation, using a tracked shipping method.
- Tracking information: You will provide a valid tracking number to the buyer and to Grail Den within two (2) business days of shipment.
- Proper packaging: You will package the item securely and appropriately for its nature, value, and fragility.
- Export compliance: The sale and shipment of the item complies with all applicable local, state, national, and international laws, including export and import restrictions.
Failure to meet these obligations may result in account suspension, transaction reversal, and/or removal from the Marketplace.
Back to top5. Buyer Responsibilities
By purchasing an item through the Marketplace, you agree to:
- Prompt payment: Complete payment at the time of purchase. Unpaid orders will be automatically cancelled after 48 hours.
- Accurate shipping information: Provide a correct and complete shipping address. Grail Den is not responsible for items lost or delayed due to incorrect addresses provided by the buyer.
- Confirm receipt: Confirm receipt of the item within seven (7) calendar days of delivery confirmation. If no confirmation or dispute is filed within this window, the transaction will be automatically marked as complete and funds released to the seller.
- Inspect promptly: Inspect the item upon receipt and report any discrepancies, damage, or issues within the 7-day confirmation window.
- Good faith: Engage in transactions in good faith. Attempting to defraud sellers, filing false disputes, or abusing the buyer protection system may result in permanent suspension.

6. Authenticity Disclaimer
Grail Den provides AI-powered authentication analysis tools ("Deep Verify") that generate confidence scores, visual comparisons, and informational assessments. These tools are provided for informational and educational purposes only.
AI authentication scores, grades, and analysis are not professional authentication services, certified appraisals, or guarantees of authenticity, provenance, condition, or value.
Grail Den does not authenticate, appraise, grade, certify, or guarantee any item listed on the Marketplace. Buyers and sellers are solely responsible for satisfying themselves as to the authenticity, condition, and value of items before completing a transaction.
For items of significant value, we strongly recommend obtaining independent professional authentication from recognized third-party services (such as PSA, JSA, BAS, or Beckett) prior to purchase.
No Grail Den employee, contractor, AI system, or platform feature shall be construed as providing professional authentication, appraisal, or valuation services. Any reliance on Grail Den's tools or information is at your own risk.
Back to top7. Prohibited Items
The following items are strictly prohibited from being listed or sold on the Marketplace:
- Stolen property: Items known or suspected to be stolen, misappropriated, or obtained through illegal means.
- Fraudulent provenance: Items with fabricated, falsified, or intentionally misleading provenance documentation or certificates of authenticity.
- Counterfeit items: Forgeries, reproductions, or replicas marketed or described as originals or authentic items.
- Export-restricted items: Items that cannot be legally sold or shipped under applicable export control laws, cultural property laws, or international trade regulations.
- Hazardous materials: Items containing hazardous substances that cannot be safely shipped.
- Items violating third-party rights: Items that infringe upon trademarks, copyrights, or other intellectual property rights of third parties.
Grail Den reserves the right to remove any listing and suspend any account found in violation of these prohibitions, without prior notice or refund of any fees.
Back to top8. Dispute Resolution & Refunds
Disputes arising from Marketplace transactions are primarily between the buyer and the seller. Grail Den may, at its discretion, facilitate communication between parties but is not obligated to mediate or resolve disputes.
Refund Policy
- Item Not as Described: If the item materially differs from the listing description, the buyer may file a dispute within the 7-day confirmation window. If the dispute is resolved in the buyer's favor, the seller is responsible for issuing a full refund including the Buyer Protection Fee and return shipping costs.
- Item Not Received: If tracking shows the item was not delivered and the seller cannot provide proof of delivery, the seller is responsible for a full refund.
- Buyer's Remorse: Returns or refunds are not available for change of mind, buyer's remorse, or items that were accurately described. Collectibles transactions are final once the confirmation window closes.
Dispute Process
- Buyer files a dispute through the Marketplace interface within the 7-day window.
- Seller has 72 hours to respond with evidence (photos, tracking, communications).
- If parties cannot resolve the dispute, Grail Den may review the evidence and issue a non-binding recommendation.
