The document outlines Nick Pappageorge's system for successfully negotiating deals on Craigslist, called the NICK system. It consists of 4 steps: 1) Know your product by researching prices; 2) Ingratiate yourself with the seller through compliments while negotiating; 3) Crush the competition by responding quickly; 4) Know when to walk away if a deal seems unsafe or you've fallen in love with a listing. Examples are given of large discounts Nick obtained on furniture, electronics, and musical instruments through using this system on Craigslist. Safety tips are also provided such as meeting in public and maintaining anonymity.
