Surprise -- $1,600 candy bar goes unsold

Cadbury was counting on at least one Brit having a major chocolate craving -- and a big budget for filling it.

But alas, the company's $1,600 World's Most Expensive Chocolate Bar -- wrapped in pure gold leaf -- failed to garner a satisfying bid after it sat on auction in the window of London's Selfridge's department store for a week this month.

Cadbury produced the top-dollar candy to celebrate the relaunch of the Wispa Gold chocolate bar. The company ended up buying it back, and donating the "proceeds" to charity.

The absurdly priced item is a common publicity stunt, and while the gold-plated Wispa bar was a one-time, limited edition, plenty of places stateside offer customers with ultra-deep pockets the chance to show off their spending abilities.
