I once ordered an Ipod nano about 2 years ago....about 3 weeks later it still had not arrived so I took it up with paypal etc (which is quite pointless) and slated the seller on my feedback...to their credit, they replied with an apology and insisted it WAS sent....so they said they will send another.....
within 2 weeks, 2 ipod nanos arrived in the post....guess 1 just got lost in the system...oh well
