Dont know if it is already been suggested, but I think that all posts in the trader section should include the seller's location (as well as item location). This will save unnecessary posts and PM's, as well as alot of time.
Maybe SAU can have a trading template that everyone has to follow to save from people having to ask the obvious questions like location, pics etc. I have seen this implemented on other forums with great success. It will also make browsing these sections alot quicker.
EDIT: Just saw the current rules, all of this is already in the rules, but not many people are following them. Maybe a template will help as all fields can be made mandatory.
Template could take the following format:
###########################
Subject Title: FS [specify item/items]
For sale: list items
Item Condition: describe in detail, be accurate and honest
Price and price conditions: self explanatory, if you are or are not willing to separate, you must specify
Extra Info: any other details you wish to mention
Pictures: if you cannot get pictures, please state to avoid people asking for it
Contact Details: PM, phone, email etc
Location: absolute must
Delivery & Conditions of Delivery: eg pickup only, courier interstate, no COD etc
