Once again, an example of a patent not advancing the arts and sciences, as they are supposed to.
eBay implemented a feature on their site, one I have used many times, called "Buy it Now". This, if enabled by a seller, allows you to do just what it says, skip the auction and buy it right away.
MercExchange filed a patent infringement lawsuit against eBay, and won that suit, although they failed to get an injunction against eBay.
I fail to see how something as simple as Buy it Now could be patented. That is patenting an idea, something that should not be happening under the law or common sense.
