The annual "Free Cone Day" serves as a "thank you" to the brand's fans and runs from 12 PM to 8 PM here in the US (times may vary).
If you can't decide on which flavors to get/try, you can actually get right back in line and get yourself another cone and repeat as you deem necessary.
You can find your nearest Ben & Jerry's scoop shop by using their online locator here.
