that are disappearing from shelves within hours of being restocked

Fanatical Costco customers have been sent scrambling in recent weeks after a surprising product became a best seller - gold bars.

The brand is known for its out-of-the box range of bargain items, from titanic tubs of Nutella to caviar and saunas.

Now, in a surprising turn, a range of gold bars available online has seen customers clambering to get their hands on one of the nuggets - with two options weighing just 1 oz and costing in the region of $1,950.

The gold rush came as Costco pleased investors with promising quarterly returns this week.

On the earnings call Tuesday CFO Richard Galanti confessed: 'I’ve gotten a couple of calls that people have seen online that we’ve been selling one-ounce gold bars.'

'Yes, but when we load them on the site, they’re typically gone within a few hours, and we limit two per member,' he added.
