McDonald's Shamrock Shake Sweeps

 Here's how to win a Golden Shamrock Shake from McDonald's for a St. Patrick's Day celebration.

Six days after the nationwide return of the popular, mint-flavored shake, McDonald’s announced Tuesday it is auctioning off a jewel-and-diamond-encrusted 18-karat gold cup, called the Golden Shamrock Shake, with bids starting at $1.

The 10-day eBay auction ends at 5 a.m. EST on March 6 with the proceeds from the winning bid going to support Ronald McDonald House Charities, the fast-food chain said in a news release.

The cup, which has emeralds, white diamonds and yellow diamonds, is worth approximately $90,000 and it took a team of jewelers over 140 hours to make, McDonald's said.
