What to write about
We want to hear about official fee pages that no longer match our JSON, broken links, translation mistakes in the Chinese pages, and questions about a rate or translation on this site. We do not provide custom tax advice, listing copy, or a promise to answer the same day. Trademark or legal notices can use the same address and should include enough detail to identify the page at issue.
What we will not do by email
We will not run a private calculation that contradicts the public calculator, invent an unpublished rate, or pretend to be a marketplace support desk. If your question is 'how much will eBay take on this sale,' the homepage calculator is the answer we can stand behind, because it uses the same dated sources as the rest of the site.
How to use this calculator
- Email alexbuildsstudio@gmail.com. Include an official URL for rate issues, plus the date you read that page.
- Allow time for a reply. This is not a 24/7 help desk. Rate corrections are answered as soon as a small studio reasonably can.
- Use the public calculator for sale math. We will point you back to it rather than re-type the formula in a thread.
- Read the legal pages if you need policy language. Privacy, terms and the disclaimer live in the footer.
