Or at least, I could not find one. I placed an order yesterday and I wanted to talk to someone about the estimated ship date of the item, and realized that there was no number listed! After clicking through a lot of pages, I realized, that all I could do was send an email to customer service, which I did send last night already. Have not heard from them yet.

I think for such a large site, with potentially naive customers, there needs to be a phone number so that they can talk. Or at least online chat.
