Hi Steph,
Our chapter holds yard sales for fundraisers. They work out great because everyone has stuff they want to get rid of, they're easy to put together, and are all profit!
Granted, the profits probably won't be that high, but it's easy.
Contact local restaurants; many of them offer fundraisers. Papa John's does, some McDonalds do...just call around and find out the details. Many of these are pretty fuss-free too.
Bake sales are a hassle, but they make money. However, I recommend selling things other than cookies and brownies. Sell slices of no-bake cheesecake! We do this and they sell out FAST. Make sugar-free things for people like diabetics. Rice Krispy treats are good sellers too.
Around Valentines Day, make those roses that people make out of Hershey's Kisses (do you know the ones I'm talking about?) and sell them.
Hope this helps!
