I wanted to order a laptop that costs 700 euro and wanted to ask from how many years I can (at idealo)
You don't order anything at Idealo, they just forward you to some portal.
Most web shops require that they are of legal age.
From 18, from the age you can do business independently.
Such a contract is pending ineffective until a legal guardian agrees.
As a rule, you have to be complete when buying online, and since you have to enter your date of birth the first time you log in, you can't do this without cheating - you have to abide by the terms and conditions.
What if I buy it in the store?
If you are under 18, you need your parents' consent
