Here’s a nifty, little known service offered by Amazon: text message (i.e. SMS) notifications of when an Amazon order is delivered to your door, as well as when an order has been shipped, when a refund has been posted to your account, etc.. In this day and age of so-called ‘porch pirates’ (people who follow the UPS truck and steal your packages as soon as they are delivered) this is proving to be a very useful service!
