Are these emails scams?

I am trying to sell my nintendo wii on kijiji in halifax NS Canada I got two replies from people wanting me to ship them it from far away here are the two emails please tell me if they sound sketchy or I am just paranoid? I have back traced the email addresses already and they don't appear to have bad info.

Hello
How are you doing hope you are having a nice time ,I would like to let
you know that i am really interested in buying your item listed for
sale, i am buying it for my cousin who lives in USA as a birthday gift
I am adding $150CAD for the shipment I remember the last
time i sent him such an item Via fedex 3days airmail delivery that was
the amount i added for the shipment.My form of Payment is PayPal
please get back to me with your PayPal email or you send me a PayPal
Payment request so i can proceed with the Payment as soon as
possible...

second email (different person)

I believe you and I trust your words, actually I am currently in Military Camp Out of the State but I will also like to speed up this transaction because my Cousin birthday is at hand and I want the item reach it's destination as a gift. My Cosine is currently study abroad, Due to high cost of shipment through Canada Post Priority to Lagos - Nigeria, I will offer you $790 to cover both item and shipping expenses.

Moreso, since I was screwed before I prefer payment terms to go through PayPal so as to protect both buyer and seller. Get back to me with your PAYPAL email for immediate payment and if you are not PayPal user, you can set up one in few minute through PayPal website. Kindly consider the item sold to me and take off the advert from Kijiji.

I await your urgent response soonest.
Thanks

 

First one sounds fishy....second is deffinately fake.

 

Yeah I have alerted the United States military of his impersonation of a naval officer. they said they would look into it.

 

I don't expect much to come out of it. I have seen thousands of these "I'm in the military and am buying it for my cousin/brother/sister/son/daughter/father" the past few years. They started with western union money orders....guess they are now working their way thru paypal.
