Gold Shock (insane new prediction) (Ad)

World Gold Council reports: "No sign" of this catalyst slowing A whopping 73% of Americans report they're "financially stressed." Over 2.2 million Americans saw their credit score fall 100 points from late payments. And everything from Red Lobster to Walmart to CVS is closing stores. What happens next will be even worse, but could hand savvy gold investors huge gains. There IS a right way to buy gold.

And you can get into my No. 1 gold play for around $10.
