Frequently Asked Questions

How do I know if a Facebook Marketplace deal is worth it?
Screenshot the listing in Underpriced. The AI identifies the item, pulls real eBay sold data, and calculates your net profit after platform fees and shipping. If the seller's price leaves you a healthy margin, it's a buy. If not, skip it.
Is there an app to analyze Facebook Marketplace listings?
Yes — Underpriced lets you screenshot any FB Marketplace listing and instantly get eBay sold comps, profit calculations, and red flag detection. It works for any item across all categories.
How do I check what a Marketplace item is really worth?
Take a screenshot and upload it to Underpriced. It identifies the item from the photo, pulls recent completed eBay sales for comparable items, and shows you the real market value — not what the seller is asking.
