ND Center is the worst possible one. I ordered from them and wish I hadn't now.
* I ordered by paying for the 72 hour service so that I would get it quicker, but they still took 12 days to process my order.
* I specifically asked them to show me proof before they shipped the certificate so that there were no spelling mistakes or errors, but they didn't do this. There were mistakes all over the certificate, e.g. I have the world's first Master of Science in Master of Business Administration!
* There wasn't any seal on it at all. WTF!
Now I'm left with a worthless piece of paper that I paid $220 for and a hole in my pocket because I borrowed the money for it thinking I was going to get a masterpiece
Don't waste your time and money with them!
