As they hit the silver paper relentlessly, silver shortages are popping up everywhere. It won't be long:

IMPORTANT NEW NOTICE: Due to market volatility and higher demand in the entire industry, we are anticipating delays in supply of all bullion products. Please note that you can continue to place orders and prices will be guaranteed; however, cancellation fees will still be applicable regardless of the length of the delay. Consequently once inventory is received there may also be delays in processing and shipping by our vaults.
