St. Patrick’s Day celebrations are already underway, and Americans plan to spend a record $5.9 billion to celebrate this year, according to the National Retail Foundation. Most popular among 18-24-year-olds, US adults are expected spend an average of $39.65 per person on Irish-themed festivities.

Here are a few ways brands are tapping into the luck o’ the Irish this year:

Green Goodies

Few St. Patrick’s day marketing campaigns are as widely recognized as the Shamrock Shake from McDonald’s. The mint-flavored treats are offered for only a month each year, creating a FOMO sense of urgency among customers, as well as nostalgia going back to 1970.

For 2018, quick service restaurant launched a shake finder app that helps consumers find the nearest McDonald’s serving Shamrock Shakes—although Texans found themselves left out.

In Chicago, the brand created a pop-up activation that projected a giant green rainbow in Daley Plaza alongside a stand giving away free cups of the minty confection. The activation was a partnership with artist Andrew Shoben.

Breakfast got a lot greener with several other promotions across the US. Bruegger’s continued its annual tradition of offering green bagels. Krispy Kreme did the same with green donuts at participating stores.

Dunkin’ Donuts took St. Patrick’s Day beyond green icing and offered customers a chance to win a year’s worth of free donuts for sharing their holiday plans. One winner will also visit the company’s headquarters in Massachusetts.

Spirits of Ireland

Jameson whiskey is offering fans a trip for three to Ireland, where they will visit the Jameson distillery and have their name carved into the bar. To enter, 21+ fans can head to the brand’s official website and finish the sentence, “You’ve a Jameson at the bar, mates at the ready, all you’re missing is…”

Guinness is celebrating its 200th anniversary in the US with a continuation its annual tradition of cause marketing. “Give A ‘Stache’ invites adults to share photos of themselves sporting a mustache—either drawn on, grown or provided by Guinness foam—by tagging Guiness on social media and the hashtag #StacheForCharity. For every photo shared, Guinness will donate $1 (up to $100,000) to the Guinness Gives Back Fund, which supports community-focused non-profits around the country.

If you can’t make it to Ireland, booking discount finder Travelzoo is hosting a Facebook Live stream of Dublin’s annual St. Patrick’s Day parade. The Facebook stream will also be shared via Tourism Ireland’s social media pages and the Facebook pages of Travelzoo in the UK and Canada. Travelzoo said last year’s St. Patrick’s Day livestream reached three million viewers.

How about St. Patrick’s Day finance? TD Bank is running an ad on Twitter that shows users how to make a healthy green shake while promoting its mortgage lending services.
