5k for a product which is good for a online business with regard to size, outlay , mark up shipping, storage etc is peanuts although against that I’d question how many people that buy it prefer/ shop etc with a dedicated site as apposed to say buying on eBay ?
I’d suppose all other things equal would be down to cost but then do you need a dedicated site and if you did then isn’t brand as opposed to a sort of emd a better long term prospect? Only you know what it cost, it makes etc for the name as a stand alone I’d say 5k is better than you’d get from any auction or domainers? Some cynic’s may see it as all publicity for something ? If not though asking on a open forum were the potential buyer could possibly see all e.g are getting it cheap or paying to much etc is not the best way ?
