Seriously though, instead of making this fake auction, just give the price you want to sell those at. It's not like D-Photon Core is a hard item to sell.
Translation: I'm asking people what they're willing to pay for it and I won't accept anything until they're willing to pay whatever I want or even higher.
As much as I agree with @bobshlibidich and @ink, only one thing remains, and that Is this statement of @(Jay)'s
so basically, If the participants decided to enter, then It's their problem
Nothing can be done If they decided to pay over 30DTs for a D-Photon Core
