Ordered a smart cover 10/21 with an expected arrival date of 11/5 with prime shipping. Wanted it to come the same day my tablet arrives (11/4), so I changed the two day shipping to one day. My estimated delivery went from 11/5 to 12/10. Tried to contact Amazon and there is nothing they can do to put me back into the "queue" as they call it. Frustrating. There should be a big message that pops up before confirming the shipping change that it may result in delayed shipment. Amazon is becoming pretty bad when it comes to making it easy for customers to pre-order items.
