erm.. help??

Ok so I have a problem. I ordered a Macbook online off the Apple Store. See, I thought they'd deliver over the weekend because they said estimated ship within 24 hours. Apparently not. They can only deliver it on Monday. The problem is we have school on Monday - I have 2 lectures. COM 203 is 0830-1030 and COM 205 is 1500-1700. On Monday they can deliver anytime between 0930 and 2100 (STUPID RIGHT??) so I have no idea when they're going to come knocking on my door, plus it needs to be signed for - there'll be no one home. I tried to change the shipping address to Hall 11 but when I got home they had already shipped it so I can't change anything. I tracked the order and I have a few options (anyone who would like to suggest something, please enlighten me. I'd greatly appreciate it).

1) Be home during the period I don't have a lecture. Although that would mean a lot of time and money wasted travelling up and down, and I can't guarantee that even if I'm home, they'll come and deliver it.

2) Not go for Monday lectures at all and stay home the whole day (but I don't like skipping school).

3) Go for the morning lecture and skip COM 205 because what are the chances it'll arrive in the morning? (again, I don't like skipping school but I guess it's not as bad as Option 2)

4) Put up a note on my door to direct the delivery man to my neighbour's house so she'll sign for it. Problem is she won't be home the whole day, and I would still need to get back to my house to collect the Mac from her.

5) Go home after COM 205 and pray pray pray that it hasn't been delivered yet.

I don't have a problem with registering on STARS because my boyfriend has offered to lend me his laptop to register on Tues (during lect some more!) but the problem of signing for the delivery isn't solved. My order is currently located in the warehouse waiting to be delivered by the carrier to my home. I can't contact Customer Service because they only answer calls Monday - Friday 9am - 6pm. Soooo annoyinggggg.
