Is AUTHOR wrong in the post ? POST : TL;DR, won an award for a project, was listed in am email and on the prize site as $1000 but got $666. Want to email to confirm amount. 

Hello, first time posting and I'm on mobile, etc. Anyways...

For a post-graduate certificate, I had to do a major research project. We put in a lot of work, and we ended up with one of the, if not the, highest marks in class. I'm not trying to brag, but it was a massive endeavour and I was glad when it was done. 

Fast forward 6 months, and I receive an ail from the school saying that I had won an award for our major research project, donated by a prominent market research firm in the area. It looked a little sketchy (wasn't formatted correctly, things looked out of place, etc), so I emailed back and did some googling. I verified it with the awards coordinator, and on the school site. Both the awards coordinator and the school site listed the prize amount as $1000. 

Again fast forward to the awards ceremony. Huge plaque, lots of handshaking, I thank the donors, etc. I check the cheque when I get home and it's $666, not $1000. I know this is a total money grab, and it's not even that much, but it just seems very strange. 

WIBTA for checking that this amount is correct?
