actually i kinda like the bidding system and frag exchange system, most pc forums locally also have been going via bidding style for their sales thread,
it gives people a chance to own what they want base on the price that they think its worth, potential buyers can always pull out when they think the price has gone beyond what they feel they are willing to fork out on a particular piece of frag, especially when most of us here cant afford to go to shipment days because of work schedule and can never get to keep a gem in their tanks,
so even if the seller gets to sell it for a price higher then what he paid for , probably he/she should be rewarded for chionging to a shipment and choosing a nice coral and keeping it in optimum conditions until it propagate.
like what lemon said, everyone wants to profiteer to some degree when it comes to buying and selling " buyer wants to buy it cheap , seller wants to sell it high "
i think its only bad if a frag is put up for bid but it does not get the price that the seller wants and he gets his friends to bid it at a price but he still keeps it, hopefully this has not happened and wont be happening in SRC
just my 2 cents no flaming please
