I use Amazon a lot and have done so for many years. Their customer service is top notch and is something to consider when picking a merchant.

Recently, I had ordered a couple of books and was told to expect delivery on a particuar date. On that date, I checked with "where's my stuff" and learned that it was "out for delivery."  Later, in the evening and noting they still had not been delivered to me, I checked again only to find out that the package had already been delivered. Thinking that one of my neighbors had taken delivery, I asked them about it and, no, none of them received the package.

I called Amazon's service department and it was eventually determined that UPS had mistakenly delivered the package to another part of town. Amazon's response was to send out a duplicate expedited order which I received two days later - at no charge!

I'd call that exceptional service.

I use Aeris Calendar (http://www.aeriscalendar.com/). I got it for the calendar features but it's nice to have its nice weather monitoring.
