Question about Ebay "Buy It Now or Best Offer" etiquette

[jpaol99]

I have won several buy it now or best offers at 50-75% their asking price. I wouldn't find it offensive to through out 50%. Although most sellers won't accept 50% their asking price, one in ten might.
I dont think I would offer much less than 50% for a few reasons. First there price is obviously more than double what I would pay. So this usually means they think they can actually get that much and decreases the chance they will come down. I usually dont bother with those kind of people.
It also depends how long the auction has been up. I find that sometimes when there is only a day or two left on their 30 day auction, sellers are usually more apt to take lower offers.
