If anything I like is truly a deal I shut my mouth and pay the money. If it's somewhat over priced I make a offer, if it's a stupidity high price I move on. It's worked for anything I've bought, cars, parts, electronics, vacuums, whatever. I used to be amazed the stupid prices people would pay for things on eBay but folks get caught up in the auction excitement and don't want to loose. I usually buy it now, or best offer with free shipping these days. You also have to have a idea what things are worth so you know a decent deal or a rippoff.
