How about a bargain section for people to post free offers,bargains etc.
Everyone likes a good deal...........

 

There's already 2 for sale sections, 3 might be stretching it too far. Most folks selling stuff probably think they're providing a bargain as it is so it could get full pretty quick and leave the other 2 empty.

Agree that a "freebie" area might be handy but how often do you think it would be used? I reckon most folks would just fire it on ebay...
