"It took about a month to come up with my list," she said."We have a game plan."
That's because she, her husband, Jim, and her mother, Alys Rae Cahoon, had $1,000 to spend.
Zambuto won the shopping spree at Ferguson & Hassler Supermarket, Quarryville, when she bought a raffle ticket earlier this year.
The cash will help needy patients and families by providing money for transportation, food, medications, and home health equipment when insurance does not cover the costs.
It can also go to something as basic as providing sleep chairs so parents can stay with their children.
The $1,000 cash raised through the raffle and a pickup full of children's toys were taken to Johns Hopkins on Friday morning, December 11.
Paxton began selling the tickets in September and wrapped the project up on October 30. The winning ticket was pulled November 10.
"I didn't expect to win," Zambuto said.
"We do a lot of charity events," her husband added, "and we knew it was a good cause.
Zambuto spent the month clipping coupons and writing an eight-page shopping list.
"One of my daughters and I came up one day and planned the trip," she said. "We're getting a little bit of everything. I have two college students and I'm buying enough to get us through the holidays."
The three family members each worked to fill a cart. When the first cart was full, it was taken to a checkout set aside for the shopping spree.
"We started at little after 8:30 [a.m.] and it will probably take us another two hours," Zambuto said.
By the time they were finished, the three family members had filled five shopping carts.
In addition to the shopping list and collection of coupons, the family also kept track of their purchases with a calculator.
"We don't want to get finished and find we spent $500 more than we expected," Jim Zambuto said.
"This came at a good time for us," his wife said. "We have three kids in college and two of them are living off campus."
