As has been said, eBay is a study in "unpredictability" - I can watch something I think is pretty innocuous go for $100 + (thinking I'd bid $20) and then snag a "gem" for half of what I'd be willing to spend because the seller didn't give it a good description, but I had a bit of knowledge that gave me an inside edge. There is no telling with eBay. So, many factors at play; inflated starting prices, inexperienced bidders, sellers without real knowledge, buyers who know how to cherry pick, plain dumb luck. I overheard a guy the other day at a pub talking to his friend; he said that buying on eBay is like gambling. There is the thrill of chance and the bitter taste of defeat. Sometimes you win, sometimes you lose. Probably the same for sellers as it is for buyers. But like gambling; the house usually wins. Be cautious and only bet what you are willing to lose and rejoice in your bargains because others weren't as clever as you.
