Hugo, you were not "tricked". You obviously did not do your homework by investigating the site before blindly plunging in. EBay exists to make money. Period. It is not a cooperative or a charity. Anyone new to eBay must read the "terms of service", where all of the specifics are clearly stated. Perhaps your listing fee was zero (though this is hard to believe), but ebay justifiably takes a "final value fee" that is a percentage of the sale price, as does PayPal.
