First you have an amazon store with PayPal? If you use PayPal then your more than aware of what the rules are for merchants. First off, someone who buys alot of items is the sign of a red flag! Second, the person can go to jail on each count of petty larceny. As long as you have a tracking number and the value of the transaction is under the threshold of what PayPal states is not required a signature you should be fun. The asshole might take it to the next level and file a dispute with their credit card company. You need to send this moron a certified letter, stating that his ass is going to jail for each count of fraud. And follow up with it by sending him a copy of the police report. Make sure you do a background check on the asshole.
