The Make an Offer app, or MaO for short, allows visitors to make real time offers on your products. You set the acceptable price by category (% off retail) or per product ($ amount) and MaO does the rest. It will decline offers lower than the minimum price you have set. If the offer is within the acceptable amounts it will approve, let them add it to cart, and then checkout. MaO does all of this automatically with no interaction from you.
