The actual site looks fairly legit with the products, but no contact numbers and looking at map under "Contacts" , takes you to a map but zooming right in appears to take you to Yellow Cabs in Brisbane. Seems off to me, i have contacted a few of these different places albeit in Melbourne, they are straightforward to deal with and have address/shopfront open and are quite happy to answer any questions/respond to emails. I hope it was only few ounces of Silver and wish you the best chasing this one down, be interested to hear how you go!
