Keep in mind that these registration outfits generally provide kickbacks to the event as a means to get the registration business, and offer a means to the hosting organization to make a few extra dollars. This kickback can be anywhere from a dollar (typical small events) to half of the processing fee on larger events, after first subtracting the credit card fee. So when you complain, you should include the hosting organization because they share responsibility in ripping you off (so to speak). Its a racket, and as long as people pay it these fees will continue, and probably continue to increase.
