Calm down mate. It is common practise to mention some possible hits that people might be interested in, IF the seller decides to sell. Obviously it is their choice and if he choses, he has an easy list of people interested in cards from the thread!
Not everything in life and forums have a set of rules to abide by, it is a public forum!
And as for the low balling comment???? Clearly you just made that one up, because no one has said ANYTHING that even vaguely resembles a value????
Thats right its his choice and he will decide if its available, not by people putting dibs on it. Asking is a different thing as your requesting, not expecting. Thats the line in the sand for me, just a bit of courtesy.
As for the low balling, thats just from my own experience which seems to be ever increasing.
