It should be noted that half of the six products advertised at that link have been sold out. I noticed elsewhere that for $50 and $100 face bags of silver as well.

After the 1980s run up, then collapse, silver has been a bum investment. Now, I think many are looking at the Trillion-Dollar bills being passed and taking prudent action. You may be right on that "double in a year" prediction, though I am looking at it from the preservation of purchasing power aspect.
