X.COM = Paypal.com Q.COM = Qwest.com I found only 2 domain name with one letter.. Sound Weird.. Why only 2 .. How Paypal and Qwest bought the one letter domain ?
Lol Because they are Big . Even you can buy if its available mail the registrar that you wanna buy and they will send you the quote .
I own over 50 one letter domain names from other extensions. If you're interested, see my thread http://forums.digitalpoint.com/subscription.php?do=addsubscription&t=1891208 Only a few extensions offer 1 letter domains
