Markit wroteThe whole "Amazon" - post delivery thing is a riddle to me. A non-specific study (my own and fams experiences) is that about 20% of the stuff goes missing.
I ordered a Kindle and after about a week no show they sent a new one, then the original arrived after they'd refunded my dosh - they said "keep it for free"!
Lucky you, all the items I have ordered that didnt show up, never showed up haha
