Well from my experience we can get LLLL.com which are expiring for like 5 $ or even less . I got 4 expiring LLLL.com for some 10$ last month .
You must be damn lucky... as people are always on the look out for such names. I still do not believe that someone did actually sell these names to you... at such prices! I have seen the quote for such names ranging from high xxx to xxxxx! Regards, RightMan
