Make an account and then search for your textbook. Once you find the book you are looking for, make an offer to the seller. The seller can either accept or decline your offer. If they decline, they have the option to also send a new offer which you, the buyer, can choose to either accept or decline. Once a party accepts an offer, the buyer decides if they would like to pick up the book in-person or pay to have the book shipped to them. If in-person, a location, date, and time can be chosen by the buyer.
