# Compare Prices Across Marketplaces

When you are looking for a specific product, checking one marketplace at a time wastes hours and still leaves you unsure whether you found the best price. Different platforms attract different seller types: one might have bulk resellers with aggressive pricing, another might have individual sellers offering near-mint condition at a premium, and a third might surface international listings with lower base prices but higher shipping.

By running `search_listings` across multiple sources and then pulling `listing_details` on the top candidates, you can build a side-by-side comparison that accounts for price, condition, shipping, and seller reputation. The result is a clear ranking of where to buy, not just what is available.
