N=1: I order a lot from Amazon Prime. About a year ago Amazon switched to Amazon Logistics, and since then a lot of the time things that were supposed to arrive in two days arrive whenever, maybe 4 days. There is no useful tracking number like FedEx or UPS, sometimes things are listed as "delivered" in my Amazon account when they are actually "out for delivery". On one occasion something was never delivered, got refunded, re-ordered, never delivered again; finally on the third go-round it was ordered and actually delivered. Amazon has got quite way to go before it catches up with UPS or FedEx.

Cliff, I got one of your Klein bottle knitted hats for my daughter when she was about 8, and she treasures it. Do you have a Klein bottle hat, to keep your noggin warm if things get chilly at night after a quake?
