What we actually automate on each marketplace.
Only eBay offers a public listing API for third-party tools. For everything else, we prepare the listing — you paste and publish.

|---|---|---|---|

Does Garage Sail really publish to eBay automatically?
Yes. Connect your eBay account once and Garage Sail publishes directly through the official eBay Sell API — title, description, item specifics, category, photos, and price are all submitted for you.
Can it auto-post to Facebook Marketplace, Mercari, OfferUp, or Craigslist?
No — none of those marketplaces offer a public listing API for third-party tools. Garage Sail generates a marketplace-tuned listing and opens each marketplace's own composer for you to paste and publish. Any tool that claims full auto-post is either violating those marketplaces' terms or overstating what it does.
How is the price set?
From recently sold comparables, not active asking prices. You get three tiers — Quick-Sale, Fair, and Max-Profit — plus a private negotiation floor.
How much does it cost to try?
5 free listings per month, no credit card required. Paid plans unlock higher limits.
Is Garage Sail an official eBay partner?
Garage Sail integrates with eBay's public Sell API, which any developer can use. That is a technical integration, not a business partnership or endorsement.
