I agree with the person above me, .biz domain names don't really sell too well, let alone a non LLL.biz and NNN.biz.
Are you going to buy two of my LLL.biz for $10? I have a good recent experience with LLL.biz domains. Bought a lot for less than reg fee and sold them up to 2x regfee (tripple premium letters). The market for LLL.biz is bad ATM compared with $60 value in 2008
Unless you have a killer name .biz is a tough sale. You could hold on to it for a few years and things might change.
nope..ok you sell it for 2x reg fee..but that not mean that market of .biz is death.. last month i sell lot of good premium domains including lll.biz for more than 20$+ each
