A campaign creator, school or district admin have the option to promote campaigns using print flyers. All they need to do is to go to the particular campaign in the fundraiser's section and click on the "share" option and select "print flyer" from the list.
This is how any Livingtree campaign flyer should look like.
In the campaign sharing option in the first image above, you can also see a "barcode" along with a "Print Flyer". One can also print just the barcode and share it with the public. It will look like this.
