These terms cover flipperstack.siringo.com and the Reseller Pro digest, both operated by Siringo Inc., 42 Broadway Suite 1227-631, New York, NY 10004. Contact: hello@siringo.com.
Reviews, prices, fees, lot listings, estimates and max-bid figures are research to help you make your own decisions. They are estimates only, checked as of the date shown on each page, and can be out of date. They are not financial, tax or legal advice. Always confirm details on the provider's or auctioneer's own page before you buy or bid. FlipperStack is not affiliated with the platforms, auction houses or agencies it mentions unless a page says so.
Lots in the digest come from sources that permit reuse (for example the U.S. General Services Administration's public GSA Auctions data) or from sellers who share them with us. Bidding, payment, inspection and pickup happen on the seller's site under the seller's terms. We do not run auctions and are not a party to any sale.
Paid plans are sold through Gumroad, which acts as merchant of record and handles payment and sales tax. You can cancel anytime from your Gumroad receipt or library, or by emailing hello@siringo.com. Access continues until the end of the period you paid for, and then stops. If the digest is not useful to you, email us within 14 days of your first payment for a full refund. Renewals after that are not refunded, but you can cancel before the next renewal. We answer support email within 24 hours on business days.
Joining the waitlist means you agree that we may email you when new samples and the founding launch are ready. You can unsubscribe at any time by replying to any email or writing to hello@siringo.com. See our privacy policy.
The digest and downloads are for your personal or internal business use. Please don't resell or redistribute them.
We may update these terms. The date at the bottom of each page shows when the site was last updated.
