Why wouldn't you just buy mills at $0.70 each from plznate which also would support the site? I don't see why you would pay $0.20-$0.30 more from a random person you would expect to unreasonably go first to you.
Just pointing it out, check out the GP selling section, you could easily find a trusted GP seller for less than what you are offering.
You're obviously a scammer "mate". Once I mention I'll go first you're suddenly 24/7 spamming me and once I mention an OMM/PlayerAuctions you've bought 450mil within a minute. Your vouches are from 2 new players aswell, please go try and scam somewhere else.
