I find ebay to be marginally useful. You can find specialty items (i.e. 944 parts, particularly used/hard-to-find ones) there for a heck of a lot cheaper than anywhere else (usually a dealership). The downside is like Wayne said, the fees and listing procedures are terrible. The "feedback" system is absolutely worthless and not worth trusting.

You can find prices on a lot of things much cheaper than from a brick-and-mortar retailer, but not always cheaper than you could find elsewhere at online retailers. I was a user of ebay way back in 1995 when it was new/innovative but since then it's really become a haven for scammers, red tape, high fees and the same sort of problems that plague "want ads" magazines, just in an electronic format.

Try craigslist. At least it's free. Still get a lot of the same problems (unresponsive buyers/sellers, too many non-serious "tire kickers" for certain things, etc., but at least it's local and free for sellers).
