I got 2 emails from EVGA, months apart. The second one was a final warning, even though I has already cashed out.
Sounds like your typical mass emailing web server problem. Who knows where it went wrong, but I am sure EVGA had the best intentions.
I was kind of wondering if EVGA didn't send emails if the quantity of bucks was too low. Too bad he won't tell us how many bucks he lost.
