Any tips to do well in ebay?

are you looking to buy or sell? there are different things to watch for each. i'm more of a ebay buyer. i occasionally sell on ebay though. most of the time i just hunt for bargains. as a buyer, i'd say there are things that will attract my attention. pictures of the actual item is a must. measurements of the item is essentail as well. it'll also help me in making a decision if the item is described in detail. details like condition, outlook and age of item are important.
