Do you have to have some sort of public plea for a clack to even be considered by ClickClack? Seems like it.
I can assure you, not everyone who gets a clack tells everyone, so don't make any assumptions.
That approach has worked once or twice - it is not necessarily likely to work again.
Others have opened a WTB thread (with a request for a CC at cost), and been granted such by other generous GH members.
Some appear to have been picked at random by CC (shot at random by CC with a laser?).
Some get lucky in an EK drawing.
Some manage to beat the odds in those first 3 seconds of a 4grabs.
A few other have deep pockets, very deep pockets.
Everyone else just gazes in wonder at the collections of some members, and hope, and dream.
Bacon.
