I received a couple of orders from Coinabul about half a year ago, though it took about two months from the purchase to receive those. Have not ordered from there since that.

I did recently order from http://bitcoincommodities.com/  .That seller was fast (got the product about a week from order) and the prices where ok.

Ordered also from Agora Commodities around a week ago. Many seem to be telling that they are fast but I have not heard anything from them yet. Must ask soon from them if there is some kind of trouble with the order.
