Everything on this site is general educational information about selling online. It is not financial, tax or legal advice, it is not tailored to your individual circumstances, and we are not a marketplace, payment processor, broker or adviser.
Calculators use standard formulas and typical published fee and rate assumptions, which change often. Figures here are estimates to guide your thinking — never promises of sales, earnings or outcomes.
Marketplace fees, carrier rates, duty schedules and tax rules change. Always confirm the current figures with the platform, carrier or customs authority before acting on them.
To the maximum extent permitted by law, we accept no liability for decisions made based on this site's content.
The $2.95 report is a digital product delivered after payment. If it is not delivered due to a technical fault, contact us for a full refund — no questions.
Do not attempt to abuse, scrape at scale, or disrupt the service. Automated agents are welcome to use the published WebMCP manifest and free endpoints responsibly.
Every tool answers instantly from our own knowledge and calculators — no AI wait, no account. Want the deeper, personalised version? Each has a $2.95 full report.
