Influence: The Psychology of Persuasion, 3rd Edition Robert B. Cialdini I have read this book a few times after purchasing it at a bookstore. The obi (paper band) is not included. The condition is good, but please understand that this is a used book. Price negotiations are only possible if you purchase other items together and they can be shipped together, in which case we can discount the shipping cost. If you wish to do so, please let me know in the comments, not using the "bundle purchase" function. I will delete any other comments or requests for bundle purchases. Regardless of comments or any other reason, I will proceed with the transaction with the person who completes the purchase procedure, in accordance with Mercari rules. I will review the price from time to time, so I would appreciate it if you would watch and wait until it reaches your desired price. #SocialBehaviorResearchGroup #RobertBCialdini #Book #Psychology/Psychology
