What really gets to me are the "Fixed Price" sales threads that start off ...
"absolute bargain £100"
followed by two days later "reduced for quick sale £75"
and then two days after that "£50 today only" etc etc etc..
Should "Fixed price" mean just that - No price drops allowed? Otherwise the above example is just "open to offers - BIN £100"
As for "open to offers" threads... Sure, there are some names listed where I think "I wonder how much they want for that", but realistically know it's likely to be more than I'm prepared to pay (I'm a small time player).
(Yes, I know I could PM them and ask, but if they knew the answer, wouldn't they have quoted a BIN?)
Perhaps sellers could be encouraged to indicate a "minimum offer".
eg domain.co.uk open to offers - min offer £100
or domain.co.uk open to offers - min offer £100 - BIN £350
That way, it would let everyone know the kind of money expected, and would cut out the "how much do you want for ...." and "I'll off you a fiver for ..." type PMs.
Oh, and "open to offer" threads should be time limited ( to say, one week from the first posting ).
