For the third year in a row, Peapod, the country’s leading online grocer, releases its list of the top candy favored for trick-or-treating. With an array of options in chocolate, sweet, and sour candies, Peapod helps customers stock up on their Halloween favorites in time for trick-or-treaters on October 31st.

So, what will trick-or-treaters be snacking on this Halloween? According to Peapod’s sales trends, the top five Halloween candies across all Peapod’s sites are:

1. Snack Size Kit Kat Candy Bars

2. Snack Size Reese’s Peanut Butter Cups

3. Fun Size Twix Cookie Bars

4. Brach’s Candy Corn

5. Hershey’s Milk Chocolate Bars

“Shoppers come to Peapod for a convenient solution for their weekly grocery shopping, but we are always working to help with the specialty seasonal items on their lists as well,” said Spencer Baird, senior vice president of merchandising for Peapod. “The majority of our customers use their Peapod order as an opportunity to check things off their to-do list, and one thing that really stands out in October is buying candy for Halloween.”

Popular in each market are Kit Kat Candy Bars, taking the overall top spot for the third year in a row! Every region has a penchant for chocolatey treats, and the top five candies in both Chicago and New York are all chocolate varieties; the D.C. region was the only market with a non-chocolate treat snagging the top spot – Brach’s Candy Corn.
