Not able to bid thousands of dollars on eBay? McDonald's has a second cup that one lucky shamrock shake-loving winner will get to take home.
According to a release from the company, starting Feb. 25, "fans who purchase a Shamrock Shake or an OREO Shamrock McFlurry via Mobile Order & Pay in the McDonald’s App through March 6 will automatically be entered to win the lucky, one-of-a-kind piece."

The shamrock shake cups took a team of jewelers over 140 hours to create. Each cup features 150 diamonds, precious stones and 18-karat gold valued at $90,000.
