Disclosure

Last updated June 5, 2026

FlipFees is free to use. Keeping it free — and keeping the fee data current — costs time and money, so the site is supported in two ways. We want to be upfront about both.

Advertising

FlipFees may display ads served by third-party networks such as Google AdSense. These ads are clearly distinguishable from our content. We do not control which specific ads appear, and an ad appearing on FlipFees is not an endorsement by us. How advertising cookies work and how to opt out of personalized ads is explained in our Privacy Policy.

Affiliate links

Some pages may include affiliate links to tools or services we think resellers will find useful — for example shipping supplies or seller software. If you click such a link and buy something, we may earn a small commission, at no additional cost to you.

Our commitment

Money never bends the math. Our fee calculators are modeled strictly from each marketplace's published fee schedule, and no advertiser or affiliate partner can change a fee figure, a comparison, or a recommendation. If we ever suggest a product, it is because we believe it genuinely helps, and any affiliate relationship is disclosed.

No marketplace affiliation

FlipFees is independent and not affiliated with, endorsed by, or sponsored by eBay, Mercari, Poshmark, Depop, or any other marketplace. Trademarks belong to their respective owners.
