I think what will make things different in G/S these days is the internet and the power in numbers that could potentially wipe out physical inventory. let's say 100 million people worldwide bought 100oz each that's 10 billion ounces. Remember we don't invest in silver we stack it.
I bought 20 of these last weekend and they just got delivered yesterday. I bit slower than my previous purchases. Like you, I buy whatever I can when I have a bit of disposable income.
