List your item with a photo as the first thing, then price, location and delivery or collect only details. It’s better to list items singly and mention if you are prepared to do a deal if someone buys 2 or more items from you. Listing multiple items in a single post usually results in confusion…It’s important to choose the correct Tags e,g, Classifieds> For Sale or Wanted
Once the item has sold, simply remove the for sale tag and replace it with a sold one. If it is a wanted ad, again simply replace wanted with the sold tag.
Who you sell something to and for how much really is between you and the purchaser, especially as you might get multiple offers and want to take a “little” time to take the best one…rather than an I bagged it first type post.
