make your offers, best offer wins, this ends at 6:45 P.m easterm time! So for example you say ill give you 50 creds. and no one else makes an offer before 6:45, you win, but if someone makes a higher offer, you lose and must make another higher bid
Offers = Based prices, meaning, "I'll sell this for 100 credits, post here if interested" Auction = Highest bid wins, which in your case, is an auction.
