1- don't lost a custommer for nothing
-The page should be as simple as posible because there was many custommer cannot wait if the page take too long to load.
2- describe items should be short and clear, because confusing cause unhappy custommer.
3- add a line click here to see my other items in the end of the page.
4- auction many item in different categories as posible, custommer may look at 1 item, but buy other items.
5- don't over describe your item or describe none sense, experience buyer hate over describe.
