The following notice has appeared on APMEX's site when you place an order and try to go thru the checkout process.
*Attention – Due to the uncertainty in the global precious metals markets, we will not be able to accept any additional orders until the global markets re-open in Asia. We expect to be accepting orders around 6:15 pm EST. Sunday August 7th, 2011, following the market open.
IMO, typical APMEX behavior. When things get iffy APMEX closes the door. Certainly not the first time they have shut out buyers. In one way or another.
Notice on Tulving's website:
IMPORTANT: OPEN ALL WEEKEND FOR ORDERS.
I would have expected nothing less from Mr Tulving. I've placed orders with him personally on Xmas day.
