UPS My Choice- sign up for FREE!
I've used this free service for over 3 months now and have received an alert the night before each delivery (you can probably guess I do quite a bit of online shopping :) they alert you with a 2-3 hour delivery time frame and so far have been totally accurate! This free service saved me several wet/snowy/soggy packages and assured me I don't need to rush home to sign! You can even change the delivery time or location (for free!) if your not going to be home at the scheduled delivery time frame.
