Along with jumbo packs of paper towels and giant piles of pants, Costco sells one-ounce gold ingots. Now, Wells Fargo is reporting that Costco is selling as much as $200 million worth of gold bars every month. Costco started selling the gold bars last August. Demand is so great that the maximum you can buy is five per customer. As Inside Edition’s Les Trent reports, it has led to a modern-day gold rush.
