If listing similar items, I do try and put them in the same ad. But on this board, I sometimes choose to list items separately simply because you cannot edit your post after 24 hours. So after 24 hours, you have to add a reply to note that something is sold instead of striking through text or making a notation in the original or -- lo and behold -- simply changing the title. It often makes for a big mess. Who wants to wade through 30 posts just to see if a box of bullets is still available?
