Contact

I read every message, and corrections to formulas or explanations get priority.

Email

You can also reach me on LinkedIn (Raúl Vaquerizo Tortosa).

Helpful details to include

Reporting an error: the calculator, the values you entered, the result you got and the result you expected.
Suggesting a calculator: the decision it would help you make and the inputs you have available.

What I cannot help with

I cannot give individual tax, customs, legal or accounting advice, or quote shipping rates. For those, contact your carrier, customs broker, accountant or marketplace support.
