Amazon Saturday Delivery Time

[craigf4656]

I have a preorder in at Amazon (US).  See, here's my problem -- I have
a 2 hour drive to make late Saturday afternoon, which means I have to
sleep the night before so no midnight party for me.

Now, I want to get as much read as I can before I have to leave -- if
possible the whole book.  But what time can I expect it to be
delivered?  Is there any reason to expect it before, say 8:00, which
would give me time to drive to the local non-24 hour Wal-Mart to buy a
copy at 7 when they open?  Or will it more likely arrive around noon,
making getting the second copy a good idea?

Thanks, and back to lurking,

Craig
