Terms of Service
Last updated: July 26, 2026
Introduction
Welcome to BidHalf (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at bidhalf.com and all associated auction and deal calculators, tools, and services (collectively, the “Service”).
By accessing or using our Service, you agree to be bound by these Terms. If you disagree with any part of these Terms, you may not access the Service.
Acceptance of Terms
By accessing, browsing, or using BidHalf, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.
We reserve the right to update or modify these Terms at any time without prior notice. Your continued use of the Service after any such changes constitutes acceptance of the new Terms.
Informational Use & Verifying Results
BidHalf provides estimates and tools for general guidance and informational purposes only. Calculator results and the guidance on the Service are informational and may be incomplete or out of date. Buyer’s premiums, sales tax, shipping, insurance, import charges, and selling-platform fees vary by auction house, marketplace, and location, and they change over time. By using the Service you agree to treat results as general estimates rather than a guarantee, and to confirm the actual fees, taxes, and terms of sale with the relevant auction house or marketplace before you bid, buy, or sell. Nothing on this site is professional financial, tax, legal, or investment advice.

Users of our tools and website agree to:
- Use the tools in good faith for legitimate personal purposes

- Not use automated systems to access our tools excessively

Your Own Judgment
You are responsible for your own bidding, buying, and selling decisions. Our tools are designed to assist and inform, not to replace your own judgment or the official terms of the auction house, marketplace, or platform you are using.
Tool Accuracy and Disclaimers
Calculation Accuracy
Our calculators are provided for informational and educational purposes only. While we strive for accuracy, we cannot guarantee that every calculation will be error-free or suitable for your specific situation. Results are estimates based on standard conventions and the figures you enter; actual costs and outcomes depend on the specific auction, marketplace, and item.
No Guarantee of Results
BidHalf makes no warranties, expressed or implied, and disclaims all other warranties including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
Financial Decisions
Estimates of profit, margin, ROI, and cost are general and informational only, are not a guarantee of any financial outcome, and are not investment or financial advice. Reselling involves risk, including the risk of loss. Always verify current fees and do your own research before you bid or sell.
Intellectual Property Rights
All content on this website, including text, graphics, logos, tools, calculators, and software, is the property of BidHalf or its content suppliers and is protected by applicable copyright laws.

Privacy and Data Protection
Your use of our website and tools is also governed by our Privacy Policy. All tool calculations happen in your browser and are not transmitted to us.
Limitation of Liability
In no event shall BidHalf or its suppliers be liable for any damages (including, without limitation, damages for loss of data, overpayment at auction, resale losses, or other financial loss) arising out of the use or inability to use the materials or tools on BidHalf, even if BidHalf or an authorised representative has been notified of the possibility of such damage.
