Hi Lee,
I am assuming the "1" would include books related to antique/ethnographic weapons of all sorts?
Regarding "3"...............often a seller is prepared to accept "reasonable offers" on an item or may not have a clue as to an items worth, OR may have several items for sale and would prefer to deal with GENUINE buyers rather than "tire kickers". I agree with all other proposed requirements of this rule but would personally prefer to see the need to state a price removed.
Also don't forget that this Forum covers "wanted" ads which it would impossible to put a price on.
While I accept the need for rules, I would not like to see things get too cumbersome or restrictive. Status quo seems to be working OK?????????
Regards Stuart
