+1 for putting price. Everytime I see a post with "offers" I move on. Just list what you want for a part so people don't waste their or your time with bad offers. If you get no bites, your price is obviously too high or your selling something that members don't need/want.
However, sometimes asking for expressions of interest, "EOI", can be usefull. We use this bit on ClubSub in New Zealand to get an idea for what we might get for parts we're replacing to help with budgeting for the upgrade parts or build.
