all 100 ounce bars will be gone within days, page-69

The only website where you can purchase perthmint products is as follows....

http://www.perthmintbullion.com/au/

The site which you refer to does not sell bullion. It only quotes buy and sell prices not offer any products for sale.

Click the 'Online Bullion Trading' link at the top of the page you are looking at and then open Silver bars tab.

100oz bars were removed from the website yesterday and I know that since I purchased one earlier in the week.

On reviewing many of the bullion products listed for sale many now show Zero in stock.

You may have more success if you call them however I suspect you will have delays in delivery until they are made.
