In honor of the shake’s 50th anniversary, McDonald’s is holding a contest where someone will win an 18-karat GOLD Shamrock Shake cup with 50 emeralds and white diamonds on it. The cup is worth $90,000…
You’ll be entered to win it every time you buy one of the shakes through the McDonald’s app.
If you just HAVE to have the cup, they’re also auctioning one off on eBay for charity. The price is up to $30,000 right now, with a little over a week to go.
