I signed up back on August 19th and canceled today, but I have yet to receive an email from letsplaywii.com confirming I would receive my Wii points. I've emailed them about it twice but they have not responded. I got the first sign up email, and their email address is added to my safe sender...
I've received 4 360 Controllers, 3 wired headsets, and one copy of Vista.
I ordered 7 copies of Vista though and the copy I received was one of the last few I ordered. And none of my accounts were zeroed. Not sure if I'll see any of the others, but whatever.
