We love CL here at my house, but you have to be very careful with meeting people and buying/selling.

It sounds like a definite scam of some sort and I don't know why someone would want to buy anything that they haven't seen in person

If it sound too good to be true....

I think they probably do have ways to scam with paypal.
I did a quick search

[Craigslist Nigerian Scams and More

Emails from Nigeria offering you more than your selling price if you accept their check or money order are typical. The fact that this is a scam may seem obvious but there are lots of variations on this theme that fool people every day. Don't add your name to the growing list of Craigslist fraud victims. Be smart, be aware and if in doubt ask your friends or someone with internet savvy what they think if things sound fishy.

This page details a few common Craigslist scams but no list is ever complete because new versions of old scams appear all the time. Once you know the common themes these criminals use you can usually spot them a mile away and they become little more than a subject of amusement.

To help keep yourself safe from scams, Craigslist advises that any business dealings be done with people in your own local area. Don't do business with folks who live far away. As with any online financial transactions, prudence and common sense are paramount. I once received an offer for a purchase where the person said they lived in California but requested that I email the item to somewhere in Oregon. Now what's wrong with this picture?

Beware of anyone offering more than what you asked for. This is too weird. Who would do that? Especially since Craigslist is known as the place to go for good deals. Other clues include poor grammar and misspelled words. In the offer I mentioned earlier both Oregon and California were misspelled and English was obviously not their native language. That doesn't necessarily mean the inquiry is coming from abroad but it's certainly a red flag.]
