Okay so im opening up my NEW DayZ Key Shop dont have many in stock as ive started not too long ago but enough to start a new shop as I dont expect to get a lot of buyers this early. I can guarantee a 12 hour warranty against the "CD Key in Use" error but I wont replace any banned keys as it would be your fault. And If I dont have a key to replace, Ill send you your money back. So there is no way you wont get a refund. I do not have an AutoBuy up yet simply because my stock is not large enough yet. Ill be on Skype most of the day. Although I do attend school from 8-3 but I will still have my phone and will be able to get you your key. Add me on Skype @ iIzChris to buy your key!!
