PLEASE READ

Once the winner is announced to me, I'll send the key within usually 12 hours, no more than 24 hours. After the key is sent, please mark it received so I can continue posting more giveaways. Please do not wait 2-7 days. You're punishing the community by doing so not me.

Although it is appreciated, it is not necessary to spam thank me in the comments. It's slightly annoying to login to 50+ notifications of the same thing.

Good luck everyone!
