help!!

i've been wanting to buy a toy for a while now but i'm scared my mom or brothers will find it. i'm 14 and my moms kind of strict(borderline neglects us but won't let us do anything normal like go to friends house) and if she found it she would kick me out. she also opens any of my packages if i'm not home when it arrives so im kind of scared about ordering one, even if it's discreet. how could i order one but hide it so she doesn't find it?
