At ebay.com there are stuff which are same but prices are different?

Well eBay is not a store where are prices of things are the same. Random people from random places sell the same things for different prices. Some could be in great condition or in bad. You see I bought a 790i xfx motherboard for $25 because the guy who sold it didn't know if it worked or not (It did :D). eBay has some greedy people and not so greedy people
