Am I getting scammed?

[strongbad]

I recently posted my Zune on craigslist, hoping to get enough money for an iPod classic since iTunes runs way better on my computer. Anyway, read the emails:

Dr. Evigan

Hello...is it still for sale let me know asap dont forget to send me some pics of it and how much are you willing to sale it

Me

Yes, the Zune is still for sale. I'm hoping to get $200 for it, but I'd be willing to go down to $180. It's in perfect condition. I had one about a year ago that recently broke, so I sent it in and got this one back, so it's virtually brand new. Attached to this email are some pictures. Tell me what you think. <insert pics here>

Dr. Evigan

As soon as I heard the word "Nigeria" I knew that something was up

one time someone on ebay bought a Mac SE from me and actually paid $2000 for overnight shipping to South Africa

but that is a scam

Either he's scamming you or you're scamming him

[Mettalik]

Well he wants to pay with PayPal, so have him send payment first before you ship

[Hiro]

Wait, your selling your delicious Zune because iTunes runs faster?

Sounds like a stolen credit card.

That, and the Zune software is deleting songs from my Zune even though they're still in my music folder.

[Hiro]

Are they in your Zune library?

[The Hand That Fisted Everyone]

They don't have computers in Nigeria

Isn't the point of craigslist to sell locally? Someone on ebay wanted to buy my PSP and have me ship it to Africa, I said no thanks.
