DIdnt think there was such a policy not being able to list many of the same items in different listings at different end dates. (with many in stock). If it is one of there policies why isnt there a notification pop up that stops me from doing it? 

I know for a fact even power sellers do this too so I dont think it would be a issue as it speeds up weekly sales rather then waiting for an auction to end before listing the next identical item.

Anyways, my point here is why doesnt ebay introduce an agreement with the buyer which states something like by bidding in this action you agree to pay the full amount if you are the winner. Not paying will lead to the buyer being charged a fee plus get a strike.

Another this is bring back the negative feed back sellers can leave on buyers.
