Why are people on E-bay so stupid?

I seriously get so mad when I'm watching something and retards keep bidding on it when it still has five days left. There's no point in bidding on something before the auction is almost over. No one cares about how high you bid until you actually win it. Everyone should not be allowed to bid on something until the final five minutes. I'm watching a test press of Cheap Shots, Youth Anthems right now and all these idiots keep bidding on it and it still has three days left. Don't they know that it will be cheaper if they just wait to place their bid until the final minutes. People on E-bay are seriously so retarded. Unless the bid you place is over $100 don't bid until the last second. It's only cool when I'm selling something and people bid all wild on it and there's still two days left.
