There's a sale thread down at the bottoms of the forum but you've gotta come up with a price to start with. I'd set the price at what you value the clams at and take it from there, you can always adjust the price if needed.
Please PM me the size of the clams and I will give you a basic idea of what they are worth.
As stated I am going to close the thread even though you have good intentions with it and I don't consider it a hype thread. If deemed OK by the other staff I will reopen it.
