I have found them on sale for as low as $2.99 (they don't last at that price...get a rain check) and the one the y did have was so small. He was around for a few weeks but just disappeared in my tank, too bad, he was so cute.
Also, have a "Fish Club Card" at one lfs so I get fish at half price so if they have Clowns I can get them for $3. (they keep losing alot of their clowns to ich) I'm waiting to add another one or two to join the one healthy one I got from them.
Average price here is about $8. (without any discount)
