We sell Poinsettia plants in Oct and get them delivered in Dec. We've done it for 20 years, so the community expects it. We made 15K last year, and we're a middle school.
The closest and BEST fundraiser I've seen is Fredricksburg Farms and their discount app. It's $20, but you get 50%, so $10 for every one sold. And their product are amazing...sold at World Market, Whole Foods, etc.
