Terms of use

1368x provides calculators and informational tools for planning purposes. By using the site, you agree to use the outputs as estimates rather than guaranteed carrier rates, eligibility determinations, financial results or professional advice.

Verify important decisions

Shipping rules, dimensions, divisors, fees, surcharges, zones and service limits can change and may differ by contract. Verify current carrier or platform rules before purchasing labels, setting store policy or making material pricing decisions.

No warranty

The site is provided on an “as is” and “as available” basis. While 1368x aims to make the calculators accurate and understandable, errors or omissions may occur.

Your responsibility

You are responsible for the data you enter and the business decisions you make from calculator outputs.

Changes

These terms may be updated as the project evolves.
