DomainReport.ca - The domain name eee.ca was auctioned today after being picked up in yesterday's TBR. The winning price for this domain was $2,550 CAD. This is a domain that expired and wasn't renewed by it's previous owner.
The appeal of this domain is that it is short, and contains all the same letter. "E" is also considered a premium letter. There are only 26 possible combinations like this, and I've never seen any come up for sale in the past.
The final price shows that short domains with special features like this one are highly regarded.
