It depends. The more I want it and the more uncommon it is the more I'll pay for it. For frags though, I swear by reef clubs.

...and that is just 1/2 of the list and doesn't include dry good buys
I have reserved the following so far:
zoas, red with blue centers and green skirts $10
green slimer $10 to replace the one I lost
If this isn't a testament to why so many of us swear by reef clubs I don't know what is.
