Q: I just want to make sure he is not a scammer or he does it illegally. he does use paypal tho http://sacramento.craigslist.org/bks/300 click on the link to see his craig's list add, he sells personal development books etc
A: The link no longer works. I would say that if you can't see something in person before you buy it, you shouldn't buy it from Craigslist. Because everything is anonymous, there is no protection against scams. If you want to buy something like that, you should use Ebay which has a lot of different mechanisms to protect against scammers.
