Where are my presents?????

I am getting really nervous now. I ordered some DVD's from half.com at the beginning of the month, and they still haven't arrived yet. They said they shipped on the 7th. That was 2 weeks ago! Come on! Don't they realize people are trying to order things for Christmas???? I have one more day to get them, and if they don't come tomorrow, I am going to be flaming mad. I am trying to decide if I should just send them back once I get them, and have them refund my money and just go buy them at the store at full-price so I can have them in time for Christmas. For the amount of shipping I paid, they could have sent them priority and I would have had them a wek and a half ago! Anyway...I had to vent somewhere. I will cross my fingers that they come tomorrow. Please!!!!!!!!!
