I bought a number of .CO domain names via NameJet / Enom last July, and I started to receive renewal notices for them a few weeks ago. I did a couple of searches, and it appears that a significant number of .CO domain names bear registration dates around July 19 – 20, 2010.
This means that the week of July 18 will be a hugely important week for the .CO Registry. Some companies are offering a .CO coupon code, but they are still relatively expensive compared to other extensions. I believe there are going to be a significant number of dropping / expiring .CO domain names in the next couple of weeks.
I know of a couple people who are interested in buying premium .CO domain names for good prices, and they would rather buy them in private than have to backorder and compete for them, or pay an extra fee for backordering the names.
If you own three letter or three number .CO domain names, or you own other GOOD keyword domain names and would like to sell them instead of renewing them, post them in the comment section below with their prices and way to contact you about buying them. It might also be a good idea to offer a bulk discount. Perhaps you can make a sale or two.
I am on vacation and posting with an iPad, so my apologies for any typos. I also may not be able to approve comments immediately.
