Books.
Books are great to sell and buy at garage sales. Buyers want to see the titles and if possible find some kind of order to your literary treasures. Organize your books into categories if possible, provide some labels and make sure the spines are arranged to show the book titles. I see no need to arrange by title or author, unless you are having a "books only" sale. Piles of books in no order attract only the serious buyers who want to thumb through them, not the casual buyer. Try sections of coffee table books, kids books, novels, text books (many people buy these to resell), cookbooks, etc. Let your inventory dictate your categories. Use boxes, bins or even laundry baskets to hold your books if you do not have bookcases. Pricing? I've seen everything from $.25 to $2, $3 or more per book, and individually priced books at higher amounts if they are of significant value. Curious about price? Check out http://www.addall.com/. TIP. If you want to sell books at your sale price them reasonably, or dirt cheap. Sell the good stuff online.
