I wait at least three weeks before worrying about not receiving a package. I need to make a button with 'life happens' on it. I would have had many many bad transactions this month if I started threatening sellers after two weeks. I got a CD that took exactly two weeks to come here from Cali today. And I still haven't gotten some box clasps I needed for my business- but you know what? I politely asked about this, and it seems that my package got sent all the way back and it has to be resent. If I had been rude, the transactions would have gotten really ugly, really fast.
