Costco has added 1-ounce platinum bars to its lineup of precious metals, priced at $1,089.99 each.

This follows the success of their gold bars, which sold out quickly after launch last year, and their silver coins, which also proved popular.

Currently available only online, platinum bar delivery is restricted in some states, including Louisiana and Nevada.

The surge in interest for precious metals among Costco shoppers aligns with growing concerns among doomsday preppers about economic instability and the potential for bartering in a post-apocalyptic scenario, the U.S. Sun has reported.

Industry experts note a significant increase in demand for small denomination gold and silver coins, which are viewed as more tradable assets.
