Ordering Online Chaos

How do I order stuff from daraz without having my pesky guards and roommates opening it?

When I was at home I used daraz to buy everything I wanted and would use their Pickup from Service Center option so no one could even find out that I ordered something and look into it. But I've moved into my university hostel now and if my guards or any of my roommates find out I'm ordering feminine stuff from Daraz, my life will be over for the next 4 years of my time here and I will be doomed for life.

I can try to avoid the guard by calling the rider personally and asking him to hand it over to someone else, but I can't avoid my hostelmates peeking into every parcel. I live with an opposite gender roommate and she knows everything about me so I don't have to hide anything from her, but the rest of the guys and girls living with us won't be considerate enough to understand my POV.

If anybody else finds out my real personality, my life at the uni would be a living nightmare.

How do I avoid them and order stuff from daraz so that nobody could know about it and I could sneak in the package to my room?
