They had a promotion where the Movie Rewards members could sign up for a free call a while back. It was expiring next week, so we used it last night.
They have a really wide variety of "pre-recorded" calls from a good selection of characters to meet any need, birthday, encouragement (the sample they had was for a dentist visit), or just a simple greeting. I chose the Goonight call by Ariel and she had quite the dialog - at least 1 minute. I even had a choice of 8 things that my daughter liked for her to reference. When you go to choose it, it shows you a text of what the call will be like, and you have the flexibility to change it before buying.
After you buy the call, you can cancel and reschedule it for another time - up to the day of.
Needless to say, my oldest was tickled!
