Costs are dated; check the date. Every fee figure on this site was recorded from the platform's own published fee or pricing page and carries a "checked" date (dataset last verified October 2026). Platforms change fees without asking us. A figure used for a real spending decision should be confirmed on the platform's current page first.
Benchmarks are planning ranges. Figures for advertising click costs, conversion rates, return rates, and time-to-first-sale are ranges drawn from published industry reporting and platform documentation, presented so you can plan conservatively. They describe typical conditions reported by others — they are not measurements of your future shop.
No earnings claims. This site makes none, anywhere: not in the finder, not in the checkers, not in the Kit. Any page or person who tells you what you will earn selling online is guessing with your money. We compute costs, fee stacks, break-even points, and downside cases — the knowable side of the ledger.
Not professional advice. Tax treatment, business licensing, product compliance, and import duties depend on your location, your products, and your facts. For those, consult a qualified professional in your jurisdiction. Our duty and fee figures are planning estimates, labeled as such wherever they appear.
Affiliate disclosure, in full: there are no affiliate links on this site and no platform pays us anything. Our only product is the First Door Kit.
