Re: Question: Can you tell a delivery person to deliver something at a specific time?
You probably got a couple ways to hide this if you didn't use your parents amazon to order it, in which case they probably will find out.
You can either tell your mom you bought a book from amazon, get another book from Barnes and noble before it comes, then when the package comes hopefully shell be trusting enough to not open it. Then grab the box open it in your room and show her the book you're not embarrassed about that you bought at b and n, and she'll be happy you're reading on your own to really care.
Or you could say it's a Christmas present for her, but might snoop around then to see what you bought her and find something more embarrassing than that. Good luck.
