Attention all Nemsters!
As far as I know the first transaction in history for a product or service in exchange for NEM has just happened.
I am awaiting product for an e-commerce site built specifically to sell NEM t-shirts. I had 15.
User gadsden76 was looking for a way to advertise NEM to his local crypto-currency group, he exchanged .1 NEMstake for a total of fifteen NEM t-shirts.
I will announce the website name where you can buy t-shirts as well once I was receive some more product.
You can view the transaction in the NXT blockchain here: http://nxtexplorer.com/nxt/nxt.cgi?action=2000&tra=16637682404186164403
