I completely second checking with your local city government on the regulations!! Last fall, I held a garage sale and wanted to sell bottle water and sodas (we’re in San Antonio, Texas after all), it gets hot. But after checking with the city, I would’ve been fine heavily because I needed a vendor license.
It’s even worse for baked goods. At my kids school, they used to have bake sales as well. But due to changes with the city, only store bought items can be sold.
So just be careful and check the local city government rules. Don’t want you to lose all of that money you earn into paying a fine. Cathy
