I did not receive one in my box either, although the box was marked that it contained the voucher. tvogel, this was for 3 free months of Skype out service.

I think that the free trial period was over, but the label was still on the box. I decide that I would just let it go...turns out the Skype out service is $3 per month, so I decided it was not worth the hassle.
