How to get a package delivered to you from Snapdeal without your family knowing?

So I wanted to buy something, a surprise gift, and I don't want my family to know about it. Now how do I get the package without the family knowing? Can I contact them and ask them to deliver at a specific time when nobody is home? And if I do that, will I be guaranteed that they arrive at that particular time? So how to be sure? Or are there any locker systems where I can store it? I am talking about Navi Mumbai here. Any help is appreciated. Thank you!
