Her family also helps out by making cookies and brownies for the effort. Two years ago, Dunkley's mother made chocolate chip cookies that sold so fast, she had to run back home and make another batch.
She's had help staffing the stand from her fourth-grader brother, a cousin and a Fresh Air kid.
Dunkley's mother said she's very proud of her daughter, and her grandmother added, "It's nice to be dedicated to something like this that helps other people."
The family no longer has a supplier for Alex's Lemonade, so they make do with canned lemonade but still forward their earnings to the foundation.
This year, the foundation sent pledge sheets that are available at Sullivan's. When a donation is made, the contributor can put their name on the sheet for display in store with other charitable souls.
The stand will run from 8 a.m. to noon. Their goal last year was $500, just like this year, and they hit $400, with a couple dollars kicked in by her mother to make it a nice round number.
Her great aunt got her started with a $50 donation, and web donations can be made at www.alexslemonade.org/mypage/74022.
