Hello Rocco Rex, I would suggest to not buy anything from Craigslist due to a lot of scary things such as:
Scammers: Some people lie to you just to rob you (literately, they will steal your money) there has been videos of people holding "customers" at gun point to rob them plus other scary things;here's some video results on those subjects: [content removed] just take a look, the results of the videos are real
I would suggest to but from either an real online retailer such as: Amazon.com, Walmart.com, bestbuy.com, ECT or going to a physical retail store. I would also not use eBay due to scary things that happen there too although the severity of scary things are significantly lower on eBay than they are on Craigslist I still wouldn't use either of those sites.
I suggest that if you must use either Craigslist or eBay use extreme caution and do extensive research on the seller, the location, the item or items being sold, and the price of the item or items. I'm not trying to scare you in anyway I'm just trying to give you some importation information of the dangers of those sites, whatever you do, do be careful.
