Yup, I figured that out, I've offered 100$ just in case, but no response till now, and there won't be one, I guess
5 characters domain, so for domain only I think it should be $20 - $30, and if there is existing PR, backlinks or anything so you should paid more than $100
money.com 5 characters, that 20-30$ too? god i love these people and their silly valuation models. a 5 letter geo.com is worth less than their xzjy.com 4 letter crap.
$1800 is also too much i think.. there are still a lot of good domain names and creation for your language.
