I've got yet another card for 2 months of free Xbox Live. I am asking for $4.00 (PayPal preferred, but...)
It is good for NEW ACCOUNTS ONLY
DSL/Cable/Broadband ONLY (I think)
USA/CANADA ONLY
Requirements can be found here: http://www.xbox.com/en-us/live/2monthfreetrial.htm
I think this is good until March 31, 2005.
