That is indeed a good price! Too many semi-scammers are fishing for the uninformed, offering down to 50% of market price.. Its a plague here, in malls, shops, kiosks, sometimes several of them in a street!
As soon as you have several customers for reputation you will have a lot of business, I am sure!
Two minor ideas:
-Special (better) rate for coins?
-Show the price in oz as well?
Since its all "too" easy to inform and compare on the internet, I suggest doing this as transparently as possible.. Realtime gold-charts, maybe a forum and the like..
Wish you luck and success, I see Bitcoins and precious metals close to each other!
Thanks for Your feedback and ideas!
We try to implement at least some of these (price in oz).
We can offer better price for coins and investment gold bars a bit later, when a site for selling them is ready and functional.
