2. About Stackex

Stackex is a marketplace that allows users to offer, sell, and buy precious metals (gold, silver, platinum, and palladium) in various geographic locations using a variety of pricing formats. Stackex is not a party to contracts for sale between third-party sellers and buyers.

Any guidance Stackex provides as part of our Services, such as pricing, shipping, listing, and sourcing, is solely informational and you may decide whether to follow it. We may use artificial intelligence or AI-powered tools and products to provide and improve our Services, offer a customized and personalized experience, provide enhanced customer service, and support fraud detection; availability and accuracy of these tools are not guaranteed.

We may help facilitate the resolution of disputes between buyers and sellers through various programs. Unless otherwise expressly provided, Stackex has no control over and does not guarantee: the existence, quality, safety, or legality of items advertised; the truth or accuracy of users' content or listings; the ability of sellers to sell items; the ability of buyers to pay for items; or that a buyer or seller will actually complete a transaction or return an item.
