The front page at Sedo.com today shows a sale reported for GMX.ca
GMX.ca - $20,000 Euros ($31,900 Cdn.)
That is a surprisingly high price for this domain at first glance. It's not yet known who the buyer is, but some speculate that the owners of GMX.com bought it. GMX.com is part of a large company that runs a webmail system. GMX is also a stock ticker symbol for Globex Mining Enterprises Inc.
No matter who the buyer was, congrats go out to the seller who appears to have negotiated a very good deal for this domain.
