This is coming strictly from a personal perspective as a buyer, not a seller, since all of my dealings on eBay have been just that as a buyer. First, there are so many scenarios, but I'll list two; the seller has a ridiculous price for something w/a BO (tons of those out there at least for what I collect) and I don't even bother negotiating or placing an offer and/or the seller has an item that is high, but not terribly unreasonable in which I will place an offer. Typically in this scenario I'll offer a price lower than I'd ultimately pay and if they accept fine and if not I can go higher, but I will not buy an item for more than I feel the item is worth.

Ultimately there are all types, both good and bad, in regard to sellers and buyers. I don't think there is a one fit answer for these type of questions. I would think that the buyer always wants to get an item for the least amount possible and the buyer wants to get as high as possible; don't think this will ever change.
