Put away small kitchen appliances and other items that are sitting on countertops and tables.
Remove photographs from table-tops.
Organize the closets.
If there's not a reason to leave something sitting around--remove it!

Store or organize items that make the yard look messy.
Make your front entry inviting. Decorate it, paint the door or buy a new door. It's the first look a buyer has when he steps up to enter.
