In honor of National Girl Scout Day on March 12 and St. Patrick's Day on March 17, Wendy's is offering free Thin Mints Frostys and Fries this week, respectively. Customers can grab the deals through the Wendy's app or website.

And what goes better with a Frosty? How about fries? Now through March 17, St. Patrick’s Day, Wendy’s is giving away free fries with a $5 purchase and drink. Again, you’ll need the app to claim the offer. As always, the deals are subject to a location’s participation, USA Today reported.

Seeing our iconic Thin Mints paired with Wendy’s Frosty is a testament to the power of the Cookie Program and millions of Girl Scouts who have made Thin Mints so popular,”
