Naive or just stupid ? Red flag this

This man or someone calling himself this,

James Harris <jamesharris240@gmail.com>

has ripped me off for the princely sum of euro 1772.00 this morning at 9.26am.

He had contacted me to purchase my late husband's electric wheelchair that I had been advertising for sale on an Austrian website.

I generated a Paypal invoice for the price I was asking for the wheelchair which was 4,500 euros.
It was sent through Paypal. I received this answer on all the correct letter heads...

I then had a series of emails from this mongrel James Harris eventually requesting me to send 1772.00 euros through Western Union to the shipper as nothing could proceed until the shipper had the details and money, at which time PayPal would release the asking price plus the extra costs for shipping.

Seems authentic enough doesn't it???
He then sent me this mail...

Hi Friend,

I have just receive an alert from PayPal Customer Care with the confirmation email that the payment has been made,a total of €6,280.00 EUR was sent,€4,500.00 EUR for the wheelchair Purchased and the extra €1,700.00 EUR for the shipping charges and am sure you notice that,the €80.00 EUR is for the western union charges,so make sure you send the money to the address below via western union.

Name : Sandra Gail Thompson

   With the issue of my details,transferring the name of ownership and signing of all paperwork will be done by the pick up agent so you don't have to worry about that.My shipper would be coming around to your area to have the wheelchair picked up once you have sent the shipping charges fee to them,as i need you to let me know what time you want them to come for the pick up . I advises you to check your Inbox or your Junk/Spam mail in case you did not get the confirmation email from PayPal yet.

I will be waiting to hear from you once the money has been sent to my shipper.

Thanks for the business 

I had no alarm bells ringing.. stupid, yes, I was so excited at the thought of selling some of Paulii's equipment that I have been storing and really want to get rid of the added bonus being that it would bring me some much needed cash. Instead I have sent the requested shipping amount.
Worse still PayPal Austria are closed for business after 6pm, and Western Union are having an unforseen emergency so I can talk to nobody about this.
