a related note:
in case anyone is considering blockbuster's free trial:
i recieved two in two weeks, they shipped them a day after registration, i recieved them a little less than a week later, shipped them the next day, and they recieved them the day before my trial ran out. a week after cancelling, i noticed on my account balance three transactions of $21.79 for BLOCKBUSTERDVD, and an email saying that i had three dvds that i had not returned, ones that i was never sent, and also that i had never queued. it was relatively simple to resolve, i called and was put on hold for approximately 20 minutes, and the gentleman was apologetic and fixed everything.
also: someone mentioned the possibility of account highjacktion and i checked, it was not.
