Costco
- Costco sells millions of dollars of gold bars a month.
- While the bars get snapped up quickly, shoppers are learning that buying is easier than reselling.
- Trading commodities, as it turns out, is full of complications.
Whenever Costco releases a batch of gold bars for sale, the supply sells out "within a few hours" as shoppers snap up the precious metal for a small markup over its spot price.
