Sorry but to give an honest answer on this:
There is just no point in a company attempting to brand on GreyChinos.com. It is not distinctive or individual.
There is little point on an affiliate attempting to build a separate site on GreyChinos.com, because the affiliate commissions available in this niche cannot justify a separate site strategy. You only need a page on your shopping related site, e.g. like my lowprices.co.uk.
So, in my opinion, it is a low value domain and extremely hard to sell.
Good luck with them anyway.
