How do you get something delivered to your house without your parents knowing?

its not a good idea, however you go about it here is allways a high chance they will get to it first.

sometimes when your ordering something to be delivered you can add additional delivery details where you could state for the delivery dude to put it somewhere outside your house that isn't too suspiciouse like 'bury it in the garden'.

or just get it sent to a friends house.

peace
