I check my email today and find Amazon set me a letter saying they mailed the rest of my order yesterday and it should arrive today. I checked the tracking numbers. Sure enough the first shipment is still about 100 miles away from me and the second one is on the delivery truck here in town and I should get it any time now.
I just find it a bit amusing that the package mailed later is going to get here first. Then again, sometimes I can be easily amused.
