ebay, the epitome of "caveat emptor"
Ebay USED to be a place where you could buy 1 of a kind, or used merchandise from private parties who are just getting rid of stuff they no longer need. Now there are thousands of would-be internet e-tailers operating out of their bedroom, these people by and large are lazy, stupid, get rich quick types who have no real investment in any retail establishment, no capital, no server of their own. In short, they use YOU to fund their operation, since no bank is dumb enough to loan them startup capital, they put things up for sale that they dont even posess yet. When you "win" an auction, they then wait for you to pay them so they can go buy the item you want. Any internet retailer that can't ship most items the next day is scamming you. Not to mention the fact that most used items on ebay sell for almost as much (sometimes more, due to fraud or just plain stupidity) as an identical new one!
Many of the ebayPros (or whatever they call these cretins that sell lots of stuff on ebay) use multiple accounts, or have friends bid their items up, especially on no reserve auctions. (thats why so many people notice that items on ebayseem to go for inflated prices).
The other new phenomenae is what a great way to fence stolen goods ebay is! The San Jose Mercury News ran a story on high tech crime, the San Jose computer crime task force told the reporter that they suspect upwards of 5% of all ebay transactions include STOLEN property. In fact, whenever cops investigate computer thefts in San Jose, the FIRST place they look is on EBAY!
Moral of the story? Use ebay for what its good for: Unique, rare, or one of a kind items, everything else (like sport headlights LOL) can be had cheaper, and FASTER (ever noticed how long it takes most of these ebayers to ship???) elsewhere.
