Deal Calculator

Paste a listing URL or pick the reference and enter the asking price by hand. Either path gets you a band, a deal tier, and a landed-cost estimate. No account, no signup.

The result is an estimate from public comparable sales. FX rates and the duty model are prototype-fixed. The calculator does NOT make accusations or label a seller. It scores the price against the market.
We fetch the listing once, server-side, with no cookies and no account. Nothing about your visit is sent to the marketplace; they see a single anonymous request from our server.
