well. if you picked the cheaper delivery option like i did... it would arrive in around 15 days time based on my past experience. and it just might not arrive at all. i have had one delivery missing in the past. though zagg guys would send you another one. you just need to pay for shipping. this is what happened when my order did not arrive for a month in the past. this is actually open to abuse as i believe there are no tracking on the cheaper delivery. you can technically get a second unit free by just paying the shipping.
not sure if they have any way to track if the original shipment was delivered at all for the cheaper delivery method.
