McDonald's has brought back their famed Shamrock Shake in time for St. Patrick's Day.
But a version on sale on eBay will cost even more green.
McDonald's is auctioning off a golden Shamrock Shake served in an emerald and diamond-encrusted 18-karat gold cup.
Bids start at a dollar, but the fast-food restaurant says the luxury drink is worth $90,000.
The pricey promotion goes along with the 50th anniversary of the Shamrock Shake. Proceeds from the winning bid will go to the Ronald McDonald House charities.
